[U-Boot] [PATCH] board/mpl: Remove mpl-specific memory test command
Peter Tyser

Wed Oct 6 06:48:47 CEST 2010
The mpl-specfic memory test is only documented for one board, doesn't
compile cleanly, uses improper coding style, and overlaps functionality
with U-Boot's common 'mtest' command, so lets get rid of it.

The few snippets of code I looked at in board/mpl were extremely ugly; I'm
assuming these board ports aren't really maintained. Would anyone
complain if I removed them?
Note I didn't compile test for the vcma9, but did compile the other
boards.
