+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+This is a /dev/crypto device driver, equivalent to those in OpenBSD or
+FreeBSD. The main idea is to access of existing ciphers in kernel space

+=== How to combine with cryptographic libraries ===
+
+* GnuTLS: 
+
+GnuTLS needs to be compiled with --enable-cryptodev in order to take
+advantage of /dev/crypto. GnuTLS 3.0.14 or later is recommended.
+
+* OpenSSL:
+
+The current releases of openssl support /dev/crypto by replacing
+eng_cryptodev.c with the version available in the extras subdirectory. 
+In order to compile use the -DHAVE_CRYPTODEV -DUSE_CRYPTODEV_DIGESTS flags.

+	changes are not that old-os friendly.
+	
+	Force OCF to select HW/SW,  otherwise it may get stuck on the first
+	device.  This change means we will favour HW over SW,  but we will
+	use both as required.  Passing in a crid of 0 to crypto_newsession
+	effectively meant we were stuck on the first device registered with
+	OCF,  not good.  This only applied to ipsec,  cryptodev already did
+	the right thing.

+	static buf but I'd like to avoid a memory copy. The following patch
+	(Physically_Contig_Rand.patch) allows me to avoid a memory copy and

+
+2006-05-25 21:06  davidm

+	* safe/: safe.c, safevar.h: 
+	
+	Safenet 1141 v1.0 chips have a DMA lockup error if you access the

+	products have v1.0 chips and would lockup with more than two
+	outstanding packets at one time.
+	
+	Fix the KASSERT macro

+	General code cleanups.
+
+2006-03-15 21:55  davidm
+
+	* hifn/hifn7751.c:

+
+2006-03-09 20:42  davidm
+
+	* ixp4xx/ixp4xx.c: 
+	
+	If we call ixpCryptoAccInit() and it fails,  just assume that it

+
+2006-02-25 08:44  davidm
+
+	* crypto.c: 
+	
+	We were calling the "process"routines with interrupts disabled.  I
+	can see no good reason for this and it provokes badness warnings in
+	2.6 under some conditions.
+	
+	I am going to run with the Q's unlocked for processing,  and
+	hopefully it will allow the system to be more responsive.  It
+	hasn't affected ipsec throughput in any way.  Userland throughput
+	(multi threaded) may have improved significantly though,  but it
+	needs more testing.
+
+2006-02-24 23:32  davidm
+
+	* cryptodev.c:

+	Whoa,  set the segments with uninitted values can't be good.  Clean

+
+2006-02-22 01:02  davidm
+
+	* cryptodev.c: 
+	
+	Still not sure about this one,	but this is working for all the

+
+2006-01-24 20:08  davidm
+
+	* crypto.c, cryptodev.c, hifn/hifn7751.c:

+	We implement our own open in the CRIOGET ioctl now which does

+
+2005-07-27 06:23  davidm
+

+	
+	udelay doesn't give up the current thread, thus the kernel will get

+
+2005-06-25 01:13  davidm

+	Run all the random numbers through SHA1 process to ensure more

+	More tracking or potential errors.
+
+2005-06-15 01:55  davidm

+	
+	Only zero data that needs to be zeroed (save some cycles)
+
+2005-06-02 21:42  davidm
+
+	* ixp4xx/ixp4xx.c:

+
+2005-06-01 02:13  davidm
+
+	* ixp4xx/ixp4xx.c: 
+	
+	Looks like I found the ixp bug.  Using OSAL buffer routines on
+	non-OSAL buffers is a very very bad thing to do.  Must double check
+	all the API's I am using (ie., PKE) just to be sure.

+2005-05-31 21:18  gerg
+
+	* Config.in:

+
+2004-11-27 09:16  davidm
+
+	* crypto.c, cryptodev.c, ixp4xx/ixp4xx.c: 
+	Fixed some nasty problems that were stopping reliable behaviour:
+	
+	1) we were not initialising some of our lists/wait queues,  which  
+	 meant they appears to have things in them when in fact they did
+	not.	 This actually didn't seems to cause any problems but is
+	extremely bogus.
+	
+	2) While a process was waiting for the crypto engine,  if
+	itreceived a	signal we would lose sync with the engine and end
+	up allowing out-of-band    actions that were invalid (ie.,
+	unregistering a context that was still	  active in a crypto
+	operation).
+	
+	   Of source the CryptACC should probably deal with this as well
+	;-)

+
+	* hifn/hifn7751.c: 
+	Changed all the accesses to DMS descriptors to not set the valid
+	bit until after everything else was set.  This got the driver
+	running smoothly, along with a fixup to the pci_map_uio which
+	wasn't settings lengths correctly.
+	
+	
+
+2004-11-25 21:15  davidm
+
+	* ixp4xx/ixp4xx.c:

+ *  -----
+ *  Flags is the bitwise "or" values for command configuration.  A single
+ *  encrypt direction needs to be set:
+ *
+ *	HIFN_ENCODE or HIFN_DECODE
+ *
+ *  To use cryptography, a single crypto algorithm must be included:
+ *
+ *	HIFN_CRYPT_3DES or HIFN_CRYPT_DES
+ *
+ *  To use authentication is used, a single MAC algorithm must be included:
+ *
+ *	HIFN_MAC_MD5 or HIFN_MAC_SHA1
+ *
+ *  By default MD5 uses a 16 byte hash and SHA-1 uses a 20 byte hash.
+ *  If the value below is set, hash values are truncated or assumed
+ *  truncated to 12 bytes:
+ *
+ *	HIFN_MAC_TRUNC
+ *
+ *  Keys for encryption and authentication can be sent as part of a command,
+ *  or the last key value used with a particular session can be retrieved
+ *  and used again if either of these flags are not specified.
+ *
+ *	HIFN_CRYPT_NEW_KEY, HIFN_MAC_NEW_KEY
+ *
+ *  session_num
+ *  -----------
+ *  A number between 0 and 2048 (for DRAM models) or a number between
+ *  0 and 768 (for SRAM models).  Those who don't want to use session
+ *  numbers should leave value at zero and send a new crypt key and/or
+ *  new MAC key on every command.  If you use session numbers and
+ *  don't send a key with a command, the last key sent for that same
+ *  session number will be used.
+ *
+ *  Warning:  Using session numbers and multiboard at the same time
+ *            is currently broken.
+ *
+ *  mbuf
+ *  ----
+ *  Either fill in the mbuf pointer and npa=0 or
+ *	 fill packp[] and packl[] and set npa to > 0
+ *
+ *  mac_header_skip
+ *  ---------------
+ *  The number of bytes of the source_buf that are skipped over before
+ *  authentication begins.  This must be a number between 0 and 2^16-1
+ *  and can be used by IPsec implementers to skip over IP headers.
+ *  *** Value ignored if authentication not used ***
+ *
+ *  crypt_header_skip
+ *  -----------------
+ *  The number of bytes of the source_buf that are skipped over before
+ *  the cryptographic operation begins.  This must be a number between 0
+ *  and 2^16-1.  For IPsec, this number will always be 8 bytes larger
+ *  than the auth_header_skip (to skip over the ESP header).

+ *
+ *  Defines for negative error codes are:
+ *
+ *    HIFN_CRYPTO_BAD_INPUT  :  The passed in command had invalid settings.
+ *    HIFN_CRYPTO_RINGS_FULL :  All DMA rings were full and non-blocking

+* mvDramIfDetect - Prepare DRAM interface configuration values.
+*
+* DESCRIPTION:
+*       This function implements the full DRAM detection and timing
+*       configuration for best system performance.
+*       Since this routine runs from a ROM device (Boot Flash), its stack
+*       resides on RAM, that might be the system DRAM. Changing DRAM
+*       configuration values while keeping vital data in DRAM is risky. That
+*       is why the function does not preform the configuration setting but
+*       prepare those in predefined 32bit registers (in this case IDMA
+*       registers are used) for other routine to perform the settings.
+*       The function will call for board DRAM SPD information for each DRAM
+*       chip select. The function will then analyze those SPD parameters of
+*       all DRAM banks in order to decide on DRAM configuration compatible
+*       for all DRAM banks.
+*       The function will set the CPU DRAM address decode registers.
+*       Note: This routine prepares values that will overide configuration of
+*       mvDramBasicAsmInit().
+*
+* INPUT:
+*       forcedCl - Forced CAL Latency. If equal to zero, do not force.
+*
+* OUTPUT:
+*       None.
+*
+* RETURN:
+*       None.

+* mvDramIfBasicInit - Basic initialization of DRAM interface
+*
+* DESCRIPTION:
+*       The function will initialize the DRAM for basic usage. The function
+*       will use the TWSI assembly API to extract DIMM parameters according
+*       to which DRAM interface will be initialized.
+*       The function referes to the following DRAM parameters:
+*       1) DIMM is registered or not.
+*       2) DIMM width detection.
+*       3) DIMM density.
+*
+* INPUT:
+*       r3 - required size for initial DRAM.
+*
+* OUTPUT:
+*       None.
+*
+* RETURN:
+*       None.
+*
+*       Note:
+*       r4 holds I2C EEPROM address
+*       r5 holds SDRAM register base address
+*	r7 holds returned values
+*       r8 holds SDRAM various configuration registers value.
+*       r11 holds return function address.

+*       configuration values while keeping vital data in DRAM is risky. That
+*       is why the function does not preform the configuration setting but
+*       prepare those in predefined 32bit registers (in this case IDMA
+*       registers are used) for other routine to perform the settings.
+*       The function will call for board DRAM SPD information for each DRAM
+*       chip select. The function will then analyze those SPD parameters of
+*       all DRAM banks in order to decide on DRAM configuration compatible
+*       for all DRAM banks.
+*       The function will set the CPU DRAM address decode registers.

+* mvDramIfBasicInit - Basic initialization of DRAM interface
+*
+* DESCRIPTION:
+*       The function will initialize the DRAM for basic usage. The function
+*       will use the TWSI assembly API to extract DIMM parameters according
+*       to which DRAM interface will be initialized.
+*       The function referes to the following DRAM parameters:
+*       1) DIMM is registered or not.
+*       2) DIMM width detection.
+*       3) DIMM density.
+*
+* INPUT:
+*       r3 - required size for initial DRAM.
+*
+* OUTPUT:
+*       None.
+*
+* RETURN:
+*       None.
+*
+*       Note:
+*       r4 holds I2C EEPROM address
+*       r5 holds SDRAM register base address
+*	r7 holds returned values
+*       r8 holds SDRAM various configuration registers value.
+*       r11 holds return function address.

+* mvEth.c - Marvell's Gigabit Ethernet controller low level driver
+*
+* DESCRIPTION:
+*       This file introduce OS independent APIs to Marvell's Gigabit Ethernet
+*       controller. This Gigabit Ethernet Controller driver API controls
+*       1) Operations (i.e. port Init, Finish, Up, Down, PhyReset etc').
+*       2) Data flow (i.e. port Send, Receive etc').
+*       3) MAC Filtering functions (ethSetMcastAddr, ethSetRxFilterMode, etc.)
+*       4) MIB counters support (ethReadMibCounter)
+*       5) Debug functions (ethPortRegs, ethPortCounters, ethPortQueues, etc.)
+*       Each Gigabit Ethernet port is controlled via ETH_PORT_CTRL struct.
+*       This struct includes configuration information as well as driver
+*       internal data needed for its operations.
+*
+*       Supported Features:
+*       - OS independent. All required OS services are implemented via external
+*       OS dependent components (like osLayer or ethOsg)

+*
+*  Assumptions :
+*				Bar0 is always internal registers bar
+*			    Bar1 is always the DRAM bar
+*				Bar2 is always the Device bar
+*
+*  1) Sets the Internal registers bar base by obtaining the base from
+*	  the CPU Interface
+*  2) Sets the DRAM bar base and size by getting the base and size from
+*     the CPU Interface when the size is the sum of all enabled DRAM
+*	  chip selects and the base is the base of CS0 .
+*  3) Sets the Device bar base and size by getting these values from the
+*     CPU Interface when the base is the base of the lowest base of the
+*     Device chip selects, and the
+*
+*
+* INPUT:
+*
+*       pexIf   -  PEX interface number.
+*
+*
+* OUTPUT:
+*       None.

+ *
+ * NOTES:
+ *
+ * The Freescale SEC (also known as 'talitos') resides on the
+ * internal bus, and runs asynchronous to the processor core.  It has
+ * a wide gamut of cryptographic acceleration features, including single-
+ * pass IPsec (also known as algorithm chaining).  To properly utilize
+ * all of the SEC's performance enhancing features, further reworking
+ * of higher level code (framework, applications) will be necessary.
+ *
+ * The following table shows which SEC version is present in which devices:
+ *
+ * Devices       SEC version
+ *
+ * 8272, 8248    SEC 1.0
+ * 885, 875      SEC 1.2
+ * 8555E, 8541E  SEC 2.0
+ * 8349E         SEC 2.01
+ * 8548E         SEC 2.1
+ *
+ * The following table shows the features offered by each SEC version:
+ *
+ * 	                       Max.   chan-
+ * version  Bus I/F       Clock  nels  DEU AESU AFEU MDEU PKEU RNG KEU

+ * SEC 1.2  internal 32b   66MHz   1     1    1    0    1    0   0   0
+ * SEC 2.0  internal 64b  166MHz   4     1    1    1    1    1   1   0

+ *
+ * Each execution unit in the SEC has two modes of execution; channel and
+ * slave/debug.  This driver employs the channel infrastructure in the
+ * device for convenience.  Only the RNG is directly accessed due to the
+ * convenience of its random fifo pool.  The relationship between the
+ * channels and execution units is depicted in the following diagram:
+ *

+ *    -------   ------------
+ *
+ * Channel ch0 may drive an aes operation to the aes unit (AESU),
+ * and, at the same time, ch1 may drive a message digest operation
+ * to the mdeu. Each channel has an input descriptor FIFO, and the
+ * FIFO can contain, e.g. on the 8541E, up to 24 entries, before a
+ * a buffer overrun error is triggered. The controller is responsible
+ * for fetching the data from descriptor pointers, and passing the
+ * data to the appropriate EUs. The controller also writes the
+ * cryptographic operation's result to memory. The SEC notifies
+ * completion by triggering an interrupt and/or setting the 1st byte
+ * of the hdr field to 0xff.
+ *
+ * TODO:
+ * o support more algorithms
+ * o support more versions of the SEC
+ * o add support for linux 2.4
+ * o scatter-gather (sg) support
+ * o add support for public key ops (PKEU)
+ * o add statistics

+/*
+ * This file defines five types of data structures: singly-linked lists,
+ * lists, simple queues, tail queues, and circular queues.
+ *
+ *
+ * A singly-linked list is headed by a single forward pointer. The elements
+ * are singly linked for minimum space and pointer manipulation overhead at
+ * the expense of O(n) removal for arbitrary elements. New elements can be
+ * added to the list after an existing element or at the head of the list.
+ * Elements being removed from the head of the list should use the explicit
+ * macro for this purpose for optimum efficiency. A singly-linked list may
+ * only be traversed in the forward direction.  Singly-linked lists are ideal
+ * for applications with large datasets and few or no removals or for
+ * implementing a LIFO queue.
+ *
+ * A list is headed by a single forward pointer (or an array of forward
+ * pointers for a hash table header). The elements are doubly linked
+ * so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before
+ * or after an existing element or at the head of the list. A list
+ * may only be traversed in the forward direction.
+ *
+ * A simple queue is headed by a pair of pointers, one the head of the
+ * list and the other to the tail of the list. The elements are singly
+ * linked to save space, so elements can only be removed from the
+ * head of the list. New elements can be added to the list before or after
+ * an existing element, at the head of the list, or at the end of the
+ * list. A simple queue may only be traversed in the forward direction.
+ *
+ * A tail queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or
+ * after an existing element, at the head of the list, or at the end of
+ * the list. A tail queue may be traversed in either direction.
+ *
+ * A circle queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or after
+ * an existing element, at the head of the list, or at the end of the list.
+ * A circle queue may be traversed in either direction, but has a more
+ * complex end of list detection.
+ *
+ * For details on the use of these macros, see the queue(3) manual page.

+	help
+	Aufs has two methods to provide a merged view for a directory,
+	by a user-space library and by kernel-space natively. The latter
+	is always enabled but sometimes large and slow.
+	If you enable this option, install the library in aufs2-util
+	package, and set some environment variables for your readdir(3),
+	then the work will be handled in user-space which generally
+	shows better performance in most cases.
+	See detail in aufs.5.
+
+config AUFS_PROC_MAP
+	bool "support for /proc/maps and lsof(1)"
+	depends on PROC_FS
+	help
+	When you issue mmap(2) in aufs, it is actually a direct mmap(2)
+	call to the file on the branch fs since the file in aufs is
+	purely virtual. And the file path printed in /proc/maps (and
+	others) will be the path on the branch fs. In most cases, it
+	does no harm. But some utilities like lsof(1) may confuse since
+	the utility or user may expect the file path in aufs to be
+	printed.
+	To address this issue, aufs provides a patch which introduces a
+	new member called vm_prfile into struct vm_are_struct. The patch
+	is meaningless without enabling this configuration since nobody
+	sets the new vm_prfile member.
+	If you don't apply the patch, then enabling this configuration
+	will cause a compile error.
+	This approach is fragile since if someone else make some changes
+	around vm_file, then vm_prfile may not work anymore. As a
+	workaround such case, aufs provides this configuration. If you
+	disable it, then lsof(1) may produce incorrect result but the
+	problem will be gone even if the aufs patch is applied (I hope).
+
+config AUFS_SP_IATTR
+	bool "Respect the attributes (mtime/ctime mainly) of special files"
+	help
+	When you write something to a special file, some attributes of it
+	(mtime/ctime mainly) may be updated. Generally such updates are
+	less important (actually some device drivers and NFS ignore
+	it). But some applications (such like test program) requires
+	such updates. If you need these updates, then enable this
+	configuration which introduces some overhead.
+	Currently this configuration handles FIFO only.
+
+config AUFS_SHWH
+	bool "Show whiteouts"
+	help
+	If you want to make the whiteouts in aufs visible, then enable
+	this option and specify 'shwh' mount option. Although it may
+	sounds like philosophy or something, but in technically it
+	simply shows the name of whiteout with keeping its behaviour.
+
+config AUFS_BR_RAMFS
+	bool "Ramfs (initramfs/rootfs) as an aufs branch"
+	help
+	If you want to use ramfs as an aufs branch fs, then enable this
+	option. Generally tmpfs is recommended.
+	Aufs prohibited them to be a branch fs by default, because
+	initramfs becomes unusable after switch_root or something
+	generally. If you sets initramfs as an aufs branch and boot your
+	system by switch_root, you will meet a problem easily since the
+	files in initramfs may be inaccessible.
+	Unless you are going to use ramfs as an aufs branch fs without
+	switch_root or something, leave it N.
+
+config AUFS_BR_FUSE
+	bool "Fuse fs as an aufs branch"

+	select AUFS_POLL
+	help
+	If you want to use fuse-based userspace filesystem as an aufs

+	  Btrfs is a general purpose copy-on-write filesystem with extents,
+	  writable snapshotting, support for multiple devices and many more
+	  features focused on fault tolerance, repair and easy administration.
+
+	  The filesystem disk format is no longer unstable, and it's not

+	  is a format change, file systems with a unchanged format will

-	  Btrfs is highly experimental, and THE DISK FORMAT IS NOT YET
-	  FINALIZED.  You should say N here unless you are interested in
-	  testing Btrfs with non-critical data.
+	  For more information, please see the web pages at
+	  http://btrfs.wiki.kernel.org.
 
 	  To compile this file system support as a module, choose M here. The
 	  module will be called btrfs.

+/*
+ * This module can be used to catch cases when the btrfs kernel
+ * code executes write requests to the disk that bring the file
+ * system in an inconsistent state. In such a state, a power-loss
+ * or kernel panic event would cause that the data on disk is
+ * lost or at least damaged.
+ *
+ * Code is added that examines all block write requests during
+ * runtime (including writes of the super block). Three rules
+ * are verified and an error is printed on violation of the
+ * rules:
+ * 1. It is not allowed to write a disk block which is
+ *    currently referenced by the super block (either directly
+ *    or indirectly).
+ * 2. When a super block is written, it is verified that all
+ *    referenced (directly or indirectly) blocks fulfill the
+ *    following requirements:
+ *    2a. All referenced blocks have either been present when
+ *        the file system was mounted, (i.e., they have been
+ *        referenced by the super block) or they have been
+ *        written since then and the write completion callback
+ *        was called and no write error was indicated and a
+ *        FLUSH request to the device where these blocks are
+ *        located was received and completed.
+ *    2b. All referenced blocks need to have a generation
+ *        number which is equal to the parent's number.
+ *
+ * One issue that was found using this module was that the log
+ * tree on disk became temporarily corrupted because disk blocks
+ * that had been in use for the log tree had been freed and
+ * reused too early, while being referenced by the written super
+ * block.
+ *
+ * The search term in the kernel log that can be used to filter
+ * on the existence of detected integrity issues is
+ * "btrfs: attempt".
+ *
+ * The integrity check is enabled via mount options. These
+ * mount options are only supported if the integrity check
+ * tool is compiled by defining BTRFS_FS_CHECK_INTEGRITY.
+ *
+ * Example #1, apply integrity checks to all metadata:
+ * mount /dev/sdb1 /mnt -o check_int
+ *
+ * Example #2, apply integrity checks to all metadata and
+ * to data extents:
+ * mount /dev/sdb1 /mnt -o check_int_data
+ *
+ * Example #3, apply integrity checks to all metadata and dump
+ * the tree that the super block references to kernel messages
+ * each time after a super block was written:
+ * mount /dev/sdb1 /mnt -o check_int,check_int_print_mask=263
+ *
+ * If the integrity check tool is included and activated in
+ * the mount options, plenty of kernel memory is used, and
+ * plenty of additional CPU cycles are spent. Enabling this
+ * functionality is not intended for normal use. In most
+ * cases, unless you are a btrfs developer who needs to verify
+ * the integrity of (super)-block write requests, do not
+ * enable the config option BTRFS_FS_CHECK_INTEGRITY to
+ * include and compile the integrity check tool.
+ *
+ * Expect millions of lines of information in the kernel log with an
+ * enabled check_int_print_mask. Therefore set LOG_BUF_SHIFT in the
+ * kernel config to at least 26 (which is 64MB). Usually the value is
+ * limited to 21 (which is 2MB) in init/Kconfig. The file needs to be
+ * changed like this before LOG_BUF_SHIFT can be set to a high value:
+ * config LOG_BUF_SHIFT
+ *       int "Kernel log buffer size (16 => 64KB, 17 => 128KB)"
+ *       range 12 30

- *	it returns "false" if there are many pending buffers in the queue,
- *	to detect a possible race between the driver checking for more work,
- *	and enabling callbacks.
- * virtqueue_detach_unused_buf: detach first unused buffer
- * 	vq: the struct virtqueue we're talking about.
- * 	Returns NULL or the "data" token handed to add_buf
- * virtqueue_get_vring_size: return the size of the virtqueue's vring
- *	vq: the struct virtqueue containing the vring of interest.
- *	Returns the size of the vring.

- * Locking rules are straightforward: the driver is responsible for
- * locking.  No two operations may be invoked simultaneously, with the exception
- * of virtqueue_disable_cb.

+	  In 32-bit arm, pkmap is limited resource and if kernel wants to map high page, this page will
+	  be mapped to pkmap address and shall be unmapped ASAP. In max connection test, kernel will try
+	  to grab pages and map it to address space. Sometimes, kernel will always get high pages and 
+	  run out of pkmap address. So, limit kernel to get low pages in write-begin of file system.

+	  In APNA enhancement for net DMA, a fixed-size management data structure is used to manage
+	  io vector and related pages. For some heavy conditions, a request of data transfer of big
+	  size will be issued and it is not enough to handle. Current management data for pages is 
+	  20 and I enlarge to 128 for most cases. If it is still not enough, a BUGON will be shown
+	  and then we need to consider a more dynamic solution for such case.
+
+config SYNO_CRYPTO_ASYNC_RACE_COND_FIX
+	bool "Fix the race condition when using ANPA crypto engine"
+	depends on SYNO_ALPINE
+	default y
+	help
+	  When a user wants to encrypt/decrypt data, he needs to prepare related data and then issue
+	  a request for hw crypto engine and wait for notification. In ANPA LSP, they use
+	  wait_for_completion_interruptiable() to wait crypto completion. In some cases, it will be 
+	  interrupted and then the use wakes up, frees management data memory. When HW finishes, an
+	  interrupt is issued and then raise a bottom half. In this bottom, it does know that management
+	  data is freed, so kernel panic occurs. Use wait_for_completion() for blocking wait. The drawback
+	  is the user must wait for the completion of encryption/decrytion of an unit of data.
+
+config SYNO_ALPINE_V2_5_3

+	depends on SYNO_ALPINE
+	default y
+	help
+	  When DS1515 power off, the power noise writes random value to phy,
+	  making its status invalid, and breaks the WOL function.
+	  To reduce the chance this issue occurs, we switch the PHY page to a
+	  read-only page before power off, so that the noise must switch to
+	  writable page first to make some trouble.

+	depends on SYNO_ALPINE
+	default y
+	help
+	  When using recvfile, it expects it can receive full data (not partial). If it receives partial data, file checksum
+	  will be incorrect. In alpine, if NETDMA is enabled, sometimes tcp_recvmsg will return partial data and cause recvfile
+	  behaves incorrectly. When the DMA resource can not satify request, turn to use CPU to copy data from socket buffer.
+
