Hi Srinivas,

I think your series looks good, so I pulled it into my tree and
combined with some input from [1] I got this up and running on Sony
Xperia T (msm8960 based).

I do get below prints in dmesg during probe, mount and some initial
accesses; but the code seems to retry the operations and things work
out nicely.

[  193.556540] mmcblk0: response CRC error sending r/w cmd command,
card status 0xb00


PS. please send the patch enabling AMBA to Kumar as well.
