The following is a list of files and features that are going to be
removed from the U-Boot source tree. Every entry should contain what
exactly is going away, when it will be gone, why it is being removed,
-and who is going to be doing the work. When the feature is removed
+and who is going to be doing the work. When the feature is removed
from U-Boot, its corresponding entry should also be removed from this
file.
---------------------------
-What: CONFIG_NET_MULTI option
-When: Release 2009-11
+What: Remove unused CONFIG_SYS_MEMTEST_START/END
+When: Release v2013.10
-Why: U-boot currently implements two network driver APIs. New drivers with
- the older-style implementation have not been accepted for a while, and
- this parallel system makes the code confusing and hard to augment.
+Why: As the 'mtest' command is no longer default, a number of platforms
+ have not opted to turn the command back on and thus provide unused
+ defines (which are likely to be propogated to new platforms from
+ copy/paste). Remove these defines when unused.
- All existing in-tree boards will be converted to use CONFIG_NET_MULTI
- over the span of two releases (2009-07 and 2009-09).
- In the 2009-11 release, all code that is compiled when CONFIG_NET_MULTI
- is not set will be removed, and all references to CONFIG_NET_MULTI
- will be removed, effectively making it the only API. This should
- provide ample time for out-of-tree users to adjust, and for tools on
- all architectures to be made to work with weak functions.

-What: "autoscr" command
-When: Release 2009-09
+What: Remove CONFIG_SYS_ENABLE_PADS_ALL and CONFIG_SYS_CLOCKS_ENABLE_ALL
+When: Release v2013.07
+
+Why: When set these options enable "all" of the pads and clocks found
+ on OMAP4/5 platforms, so that the Linux Kernel does not have to.
+ It has been agreed that this goes against the U-Boot design
+ philosophy and since f3f98bb0 we have not enabled more than is
+ used in U-Boot. The kernel has been updating drivers to enable
+ rather than assume pads/clocks have been enabled already. Our
+ expectation is that by v2013.07 a suitable kernel shall exist that
+ does not need these options set for a reasonable I/O set to function.
-Why: "autosrc" is an ugly and completely non-standard name.
- The "autoscr" command is deprecated and will be replaced by
+Who: Tom Rini <trini@ti.com> and Sricharan R <r.sricharan@ti.com>
+
+---------------------------
- the "source" command as used by other shells such as bash.
+What: Users of the legacy miiphy_* code
+When: undetermined
- Starting with March 2009, both commands will be supported for
- a transition period of 6 months after which "autoscr" will be
- removed. During the transition period existing scripts and
- environment variable names remain untouched for maximum
- compatibiltiy; thse will be changed when support for the
- "autoscr" command get's finally dropped.
+Why: We now have a PHY library, which allows everyone to share PHY
+ drivers. All new drivers should use this infrastructure, and
+ all old drivers should get converted to use it.

-What: Legacy NAND code
-When: April 2009
-Why: Legacy NAND code is deprecated. Similar functionality exists in
- more recent NAND code ported from the Linux kernel.
