what you are supposed to do (2014-7-30).
* arch/arm/src/sama5/sam_hsmci.c and README files: Re-enable TX DMA and
verify that DMA writes to the SD card are functional. They are so now
TX DMA is re-enabled in the driver. This might affect the SAMA5D3
platforms where the TX DMA problem was found. The SAMA4D3 and 4 use
the same HSMCI driver. Much has change since then and it is not
surprising that DMA is now functional. However, the has not be re-
verified on the SAMA5D3 which has a different DMA controller
