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. +Who: Tom Rini -Who: Ben Warren +--------------------------- + +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. + +Who: Tom Rini and Sricharan R + +--------------------------- + +What: Users of the legacy miiphy_* code +When: undetermined + +Why: We now have a PHY library, which allows everyone to share PHY + drivers.
