1The following is a list of files and features that are going to be 2removed from the U-Boot source tree. Every entry should contain what 3exactly is going away, when it will be gone, why it is being removed, 4and who is going to be doing the work. When the feature is removed 5from U-Boot, its corresponding entry should also be removed from this 6file. 7 8--------------------------- 9What: CONFIG_SYS_ARM_WITHOUT_RELOC option 10When: After Release 2011.03 11 12Why: The implementation of U-Boot for the ARM architecture has 13 been reworked to support relocation. This allows to 14 efficiently use the same U-Boot binary image on systems with 15 different RAM sizes, and brings the implementation much more 16 in line with the code used for example on Power Architecture 17 systems (eventually allowing to merge into common code). This 18 seems especailly interesting now that ARM is getting Device 19 Tree support as well. 20 21 All ARM boards need to be adapted to this new code, which 22 requires testing on the actual hardware, so this is a task 23 for the respective board maintainers or other users. 24 25 Please see the commit message of commit f1d2b31 for details: 26 27 http://git.denx.de/?p=u-boot.git;a=commit;h=f1d2b31 28 29 Support for CONFIG_SYS_ARM_WITHOUT_RELOC will be removed 30 after release v2011.03; all boards that have not been 31 converted by then, i. e. that are still broken then, are 32 considered unmaintained and without interest for the 33 community and will be removed as well. 34 35--------------------------- 36 37What: CONFIG_NET_MULTI option 38When: Release 2009-11 39 40Why: U-boot currently implements two network driver APIs. New drivers with 41 the older-style implementation have not been accepted for a while, and 42 this parallel system makes the code confusing and hard to augment. 43 44 All existing in-tree boards will be converted to use CONFIG_NET_MULTI 45 over the span of two releases (2009-07 and 2009-09). 46 In the 2009-11 release, all code that is compiled when CONFIG_NET_MULTI 47 is not set will be removed, and all references to CONFIG_NET_MULTI 48 will be removed, effectively making it the only API. This should 49 provide ample time for out-of-tree users to adjust, and for tools on 50 all architectures to be made to work with weak functions. 51 52Who: Ben Warren <biggerbadderben@gmail.com> 53 54--------------------------- 55 56What: GPL cleanup 57When: August 2009 58Why: Over time, a couple of files have sneaked in into the U-Boot 59 source code that are either missing a valid GPL license 60 header or that carry a license that is incompatible with the 61 GPL. 62 Such files shall be removed from the U-Boot source tree. 63 See http://www.denx.de/wiki/pub/U-Boot/TaskGplCleanup/u-boot-1.1.2-files 64 for an old and probably incomplete list of such files. 65 66Who: Wolfgang Denk <wd@denx.de> and board maintainers 67
