[U-Boot] Driver for SDHC controller on IMX27

[alfred steele]

Hi Ilya/Fabio,

I followed your guidelines for trying to use the MX27 SDHC driver/MMC
framework as the base code and make appropiate mods to make it work
on the MX31 PDK board but i have been unsuccessful till this point. i
had left this task off at a point because of higher priorities.

Do you know if there is an existing driver to make SD cards work on uboot.

Thanks,
Alfred.
