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_SYS_ARM_WITHOUT_RELOC option
|
|
When: After Release 2011.03
|
|
|
|
Why: The implementation of U-Boot for the ARM architecture has
|
|
been reworked to support relocation. This allows to
|
|
efficiently use the same U-Boot binary image on systems with
|
|
different RAM sizes, and brings the implementation much more
|
|
in line with the code used for example on Power Architecture
|
|
systems (eventually allowing to merge into common code). This
|
|
seems especailly interesting now that ARM is getting Device
|
|
Tree support as well.
|
|
|
|
All ARM boards need to be adapted to this new code, which
|
|
requires testing on the actual hardware, so this is a task
|
|
for the respective board maintainers or other users.
|
|
|
|
Please see the commit message of commit f1d2b31 for details:
|
|
|
|
http://git.denx.de/?p=u-boot.git;a=commit;h=f1d2b31
|
|
|
|
Support for CONFIG_SYS_ARM_WITHOUT_RELOC will be removed
|
|
after release v2011.03; all boards that have not been
|
|
converted by then, i. e. that are still broken then, are
|
|
considered unmaintained and without interest for the
|
|
community and will be removed as well.
|
|
|
|
---------------------------
|
|
|
|
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: 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.
