Shenghzou,
This is not a correct fix. This issue is related to
http://lists.denx.de/pipermail/u-boot/2015-December/236272.html http://lists.denx.de/pipermail/u-boot/2016-March/249377.html
In short, the invalidate_dcache_range function was added for 512x/5xxx/83xx/85xx. Although it shouldn't do any harm, it actually does. I haven't got a chance to investigate. Please look into it if you can.

York, This patch is just a quick hack, I thought root cause is needed to be dug, this issue didn't occur on ARM, just happened on PPC(e.g. T1/T2/T4 platforms). I have no time on this(occupied on ONL), suggest MMC owner continue to investigate it. Shengzhou
