This patch breaks eMMC on my TQMa6S (i.MX6SOLO). With it I get this 
error upon U-Boot update:

MMC write: dev # 0, block # 2, count 711 ... mmc write failed

With this patch reverted it looks just fine:

MMC write: dev # 0, block # 2, count 711 ... 711 blocks written: OK

Any ideas what might cause this breakage? If this issue can't be solved 
soon I suggest to revert this patch for this release.

Thanks,
Stefan
