Can we get some Tested/Reviewed/Acked-by from people using this driver?


Hi Pramod,
Thanks for the patch. Unfortunately, my db410c board fails to
boot when i apply it.

More I/O errors are following and it is unable to mount the rootfs from
the eMMC. When i retried booting, got also the following:
