Nope.  ARM reference boards all seem to have broken DMA.  I've given up
with the idea of getting DMA working on any of these platforms, and as
yet I've not had a response from the ARM Support request which Catalin
logged for me on this subject.

I don't believe it is possible for MMCI to ever work correctly with DMA
on ARM development platforms.
