Recent changes to teach SDHCI 64-bit support inadvertently changed the address used for cache maintenance away from the DMA buffer address with the result that unrelated cache lines were dropped and memory corruption. This series fixes this. I must admit I don't understand how the SDMA boundary mechanism works, so I did not change too much about it.
