[U-Boot] Enhanced sd host controller driver for the mxc platform

[stephanie keeling]

Hi,
I am trying to create/develop a device driver for the enhanced sd host
controller driver for the mxc platform, specifically the mx27/35 platforms.
This would provide a glue to the upper layers of u-boot i.e the MMC
infrstructure and the filesystem layers.
Since this will be a polling only  driver unlike the one in Linux, has
anyone tried working towards a mxc e-sdhc driver yet. I am currently looking
at the linux driver for the same. Are there any quick guidelines for porting
the interrupt based driver to a polling only driver in U-boot.

BTW, i have succesfully /implemented a SDHC driver from the scratch on the
mxc platform earlier.

Any comments/suggestions?
Thanks in advance!
-Stephanie.
