[PATCH master 0/2] mci: sdhci: fix memory corruption on DMA

[Ahmad Fatoum]

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.

  mci: sdhci: hardcode SDMA boundary for DMA
