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
from U-Boot, its corresponding entry should also be removed from this
file.
---------------------------
What: CONFIG_NET_MULTI option
When: Release 2009-11
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.
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
Why: "autosrc" is an ugly and completely non-standard name.
The "autoscr" command is deprecated and will be replaced by
the "source" command as used by other shells such as bash.
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.

---------------------------
What: GPL cleanup
When: August 2009
Why: Over time, a couple of files have sneaked in into the U-Boot
source code that are either missing a valid GPL license
header or that carry a license that is incompatible with the
GPL.
Such files shall be removed from the U-Boot source tree.
See http://www.denx.de/wiki/pub/U-Boot/TaskGplCleanup/u-boot-1.1.2-files
for an old and probably incomplete list of such files.
Who: Wolfgang Denk <wd@denx.de> and board maintainers
---------------------------
What: Individual I2C commands
When: April 2009
Why: Per the U-Boot README, individual I2C commands such as "imd", "imm",
"imw", etc are deprecated. The single "i2c" command which is
currently enabled via CONFIG_I2C_CMD_TREE contains the same
functionality as the individual I2C commands. The individual
I2C commands should be removed as well as any references to
CONFIG_I2C_CMD_TREE.

---------------------------
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.
