One other thing to be considered here is whether this idea should be
limited to just MMC or whether it should be extended further, to
move the DMA mapping stuff out of the hot path for other block devices
too.

There are ARM systems with SATA which do 28MB/s - which could be
improved by this technique.

Excellent point. We had discussed SATA items in the context of Linaro
work before, and the conclusion was always that we wouldn't need to
do any work for it in the common code. I'll make sure that we bring
it up at the meeting next month in Cambridge so we can officially
assign someone to do this.

Arnd, do you know if any of the Linaro boards have SATA?
