It took a while to get to it but here is the draft driver patch
against v4.11-rc1. Please test.

I tested this on DM6446 EVM. I was able to mount existing partitions on
the hard disk and see that the directory listing looks good[1]. I will do

I completed the tests I wanted to, including some read/write/data

Tested-by: Sekhar Nori <nsekhar@xxxxxx>

Here are the additional changes I did. These changes do not clash with

I carry the platform pieces through my tree. Let me know how you want
to proceed.

Thanks,
Sekhar
