Yes, I'm working on an iMX31 board at the moment and would love to see
DMA at the platform level too.

Take a look at ./drivers/mmc/host/mxcmmc.c -->
#ifdef CONFIG_ARCH_MX2
#include <mach/dma-mx1-mx2.h>
#define HAS_DMA
#endif
If you jiggle that around to match your DMA patch, then you should be
able to test the SD Card relatively straightforward since the same
driver is tested with DMA on those platforms presumably.
