This adds the mmc host driver for Freescale MXS-based SoC i.MX23/28.
The driver calls into mxs-dma via generic dmaengine api for both pio
and data transfer.

I've run the mmc-test kernel module with this driver on our TX28
module which fails in the following tests:
|mmc0: Test case 15. Correct xfer_size at write (start failure)...
|mmc0: Result: ERROR (-110)
|mmc0: Test case 16. Correct xfer_size at read (start failure)...
|mmc0: Result: ERROR (-110)
|mmc0: Test case 17. Correct xfer_size at write (midway failure)...
|mmc0: Result: ERROR (-110)
|mmc0: Test case 18. Correct xfer_size at read (midway failure)...
|mmc0: Result: ERROR (-110)

Could you try the test on your hardware?

I'm new to this test.  I enabled MMC_TEST but did not see "test"
under /sys for mmc.  Can you please elaborate how to launch this
test?  Thanks.

Regards,
Shawn
