Dear Dipen Dudhat,

On some Freescale SoC Internal DMA of eSDHC controller has bug.
So PIO Mode has introduced to do data transfer using CPU. In PIO mode data transfer performance will be degraded by a large extent.
Note: In PIO mode multiple block read/write requires delay to complete the transfer.

My comments to v1 of the patch still apply.
Best regards,
