On my test hardware I am getting different results with different SD and SDIO cards on different boards in different slots. The first patch in this series fixes DMA for all my available hardware, the second one is a further improvement to make switching between DMA and PIO possible at run-time on a per-transfer basis and uses PIO for short transfers also when DMA is available.
