Thanks, one can tell that I haven't done my due diligence of checking
Shawn's tree first. I'll cherry-pick that patch and carry on with my
work.

However, the fact still remains that Michael has expressed his opinion
regarding mmcblk0 vs mmcblk1. Do you think that we could make the
aliases a per-board option instead of per-SoC? Consider that there might
even be boards that only use SD card. It would be strange for the block
device in that case to be called /dev/mmcblk1.
