Please don't send this patch as base64 encoded. It makes it impossible 
to apply this patch or run checkpatch on it.

Did you run it though checkpatch btw?

I suggest to rename the driver to mvebu_mmc.c instead. This MVEBU is the 
generally agreed upon abbreviation for Marvell SoC's (Orion, Kirkwood, 
Armada XP, 370 ...).

Doesn't it make sense to move this code to init / enable the MMC driver 
into the arch/cpu/... SoC code? Instead of adding it to all the board 
specific files?

Here we have this code again. I suggest to move it to the kirkwood cpu.c 
file instead.

Thanks,
