[U-Boot-Users] [PATCH] MMC: Consolidate MMC/SD command definitions

Wed May 21 14:12:45 CEST 2008
This moves the MMC and SD Card command definitions from
include/asm/arch/mmc.h into include/mmc.h. These definitions are given
by the MMC and SD Card standards, not by any particular architecture.
There's a lot more room for consolidation in the MMC drivers which I'm
hoping to get done eventually, but this patch is a start.
Compile-tested for all avr32 boards as well as lpc2292sodimm and
lubbock. This should cover all three mmc drivers in the tree.
