My main concerns relate to board-specific setup, which might
not end up impacting the driver code as much as the code in
arch/arm/mach-omap2/hsmmc.c (and its callers).

Basically, if you look at the hsmmc.c file it's got a LOT of
board-specific stuff hard-wired.  The way it *should* work is
the board-XYZ.c file passes that into setup code ... and that
info can include things like "are all 8 data lines available?",
as well as card detect triggering and writeprotect switch
access.

There might be other issues ... but it was rather easy to
notice those problems when for example the HSMMC on a Beagle
comes up with truncated functionality.
