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.
Can we have one mmc-lite stack from linux kernel? The linux kernel have one good frame work for sd/mmc/sdio.
Yes, I was hoping we could do something like that. There's a lot of duplication in the various MMC drivers we have, and none of them support all kinds of cards AFAIK.
It would be nice with a core protocol layer which takes care of initialization and stuff, leaving only the low-level hardware stuff to the driver.
The Linux mmc framework is certainly good...but it may be too heavyweight for u-boot.
