-What: Remove CONFIG_CMD_MEMTEST from default list
-When: Release v2013.07
+What: Remove unused CONFIG_SYS_MEMTEST_START/END
+When: Release v2013.10
-Why: The "mtest" command is of little practical use (if any), and
- experience has shown that a large number of board configu-
- rations define useless or even dangerous start and end
- addresses. If not even the board maintainers are able to
- figure out which memory range can be reliably tested, how can
- we expect such from the end users? As this problem comes up
- repeatedly, we rather do not enable this command by default,
- so only people who know what they are doing will be confronted
- with it.
+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.
-Who: Wolfgang Denk <wd@denx.de>
+Who: Tom Rini <trini@ti.com>
