Peter Tyser5fc56b92009-01-30 16:36:40 -06001The 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,
Wolfgang Denkd483a222010-09-29 11:25:55 +02004and who is going to be doing the work. When the feature is removed
Peter Tyser5fc56b92009-01-30 16:36:40 -06005from U-Boot, its corresponding entry should also be removed from this
6file.

Wolfgang Denkd483a222010-09-29 11:25:55 +02009What: 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.

25 Please see the commit message of commit f1d2b31 for details:

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.

Ben Warrenc404cc52009-04-28 17:04:51 -070037What: 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.

Wolfgang Denk78237df2009-04-02 17:31:09 +020056What: 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.
