From: Felix Fietkau Date: Mon, 18 Jan 2016 11:40:19 +0000 (+0000) Subject: lantiq: Add support for linux 4.4 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f577cb25c09daad670755b9b46622258cf999421;p=openwrt%2Fstaging%2Fansuel.git lantiq: Add support for linux 4.4 The following patches were dropped because they are already applied upstream: - 0038-MIPS-lantiq-fpi-on-ar9.patch - 0039-MIPS-lantiq-initialize-usb-on-boot.patch - 0042-USB-DWC2-big-endian-support.patch - 0043-gpio-stp-xway-fix-phy-mask.patch All other patches were simply refreshed, except the following: - 0001-MIPS-lantiq-add-pcie-driver.patch Changes to arch/mips/lantiq/xway/sysctrl.c (these changes disabled some PMU gates for the vrx200 / VR9 SoCs) were removed since the upstream kernel disables unused PMU gates automatically (since 95135bfa7ead1becc2879230f72583dde2b71a0c "MIPS: Lantiq: Deactivate most of the devices by default"). - 0025-NET-MIPS-lantiq-adds-xrx200-net.patch Since OpenWrt commit 55ba20afcc2fe785146316e5be2c2473cb329885 drivers should use of_get_mac_address(). of_get_mac_address_mtd is not available for drivers anymore since it's called automatically within of_get_mac_address(). - 0028-NET-lantiq-various-etop-fixes.patch Same changes as in 0025-NET-MIPS-lantiq-adds-xrx200-net.patch While refreshing the kernel configuration SPI support had to be moved to config-4.4 because otherwise M25P80 was disabled.

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. ++ ++ END OF TERMS AND CONDITIONS +--- /dev/null ++++ b/firmware/lantiq/README +@@ -0,0 +1,45 @@ ++# ++# 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.
