I'm not sure if you tested that, but we have some code that switches
the MMC indices when using both an eMMC and an external MMC.

http://git.denx.de/?p=u-boot.git;a=blob;f=board/sunxi/board.c#l494

This predates my time, but it seems that it was done to have a
consistent boot MMC device ID.

I'm not really sure we can get rid of it (even if it creates some
issues of it's own), but what would be the impact of a switch to the
device model on that logic?

Thanks,
Maxime
