++
++		    GNU GENERAL PUBLIC LICENSE
++		       Version 2, June 1991
++
++ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
++     59 Temple Place, Suite 330, Boston, MA  02111-1307  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 Library 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.

+Subject: [PATCH 27/36] NET: add of_get_mac_address_mtd()
+
+Many embedded devices have information such as mac addresses stored inside mtd
+devices. This patch allows us to add a property inside a node describing a
+network interface. The new property points at a mtd partition with an offset
+where the mac address can be found.

+Subject: [PATCH 34/36] reset: Fix compile when reset RESET_CONTROLLER is not
+ selected
+
+Drivers need to protect their reset api calls with #ifdef to avoid compile
+errors.
+
+This patch adds dummy wrappers in the same way that linux/of.h does it.
