Revert "mkconfig: start deprecating Makefile config targets"
[people/ms/u-boot.git] / doc / feature-removal-schedule.txt
1 The following is a list of files and features that are going to be
2 removed from the U-Boot source tree. Every entry should contain what
3 exactly is going away, when it will be gone, why it is being removed,
4 and who is going to be doing the work. When the feature is removed
5 from U-Boot, its corresponding entry should also be removed from this
6 file.

10 What: Remove CONFIG_CMD_MEMTEST from default list
11 When: Release v2013.07
12
13 Why: The "mtest" command is of little practical use (if any), and
14 experience has shown that a large number of board configu-
15 rations define useless or even dangerous start and end
16 addresses. If not even the board maintainers are able to
17 figure out which memory range can be reliably tested, how can
18 we expect such from the end users? As this problem comes up
19 repeatedly, we rather do not enable this command by default,
20 so only people who know what they are doing will be confronted
21 with it.

23 Who: Wolfgang Denk <wd@denx.de>

25 ---------------------------
26
27 What: Remove CONFIG_SYS_ENABLE_PADS_ALL and CONFIG_SYS_CLOCKS_ENABLE_ALL
28 When: Release v2013.07
29
30 Why: When set these options enable "all" of the pads and clocks found
31 on OMAP4/5 platforms, so that the Linux Kernel does not have to.
32 It has been agreed that this goes against the U-Boot design
33 philosophy and since f3f98bb0 we have not enabled more than is
34 used in U-Boot. The kernel has been updating drivers to enable
35 rather than assume pads/clocks have been enabled already. Our
36 expectation is that by v2013.07 a suitable kernel shall exist that
37 does not need these options set for a reasonable I/O set to function.

39 Who: Tom Rini <trini@ti.com> and Sricharan R <r.sricharan@ti.com>
40
41 ---------------------------
42
43 What: Users of the legacy miiphy_* code
44 When: undetermined
45
46 Why: We now have a PHY library, which allows everyone to share PHY
47 drivers. All new drivers should use this infrastructure, and
48 all old drivers should get converted to use it.
49
50 Who: Andy Fleming <afleming@freescale.com> and driver maintainers
51
52 ---------------------------
53
54 What: GPL cleanup
55 When: August 2009
56 Why: Over time, a couple of files have sneaked in into the U-Boot
57 source code that are either missing a valid GPL license
58 header or that carry a license that is incompatible with the
59 GPL.
60 Such files shall be removed from the U-Boot source tree.
61 See http://www.denx.de/wiki/pub/U-Boot/TaskGplCleanup/u-boot-1.1.2-files
62 for an old and probably incomplete list of such files.

64 Who: Wolfgang Denk <wd@denx.de> and board maintainers
