mxc-mmc: sdhc host driver for MX2 and MX3 proccessor
This is a port of Linux driver for SDHC host controller hardware found on Freescale's MX2 and MX3 processors. Uses new generic MMC framework (CONFIG_GENERIC_MMC) and it looks like there are some problems with a framework (at least on LE cpus). Some of these problems are addressed in the following patches. Signed-off-by: Ilya Yanok <yanok@emcraft.com>
