OMAP3517 ALPHA: Changes for MMC2 support in Kernel
Some initialization like, Pad configuration, clock settings
needs to be done from U-Boot for MMC2 port
to be accessed from Kernel.
Please note that u-boot still only supports MMC1 Port. To enable MMC2
from U-Boot one should only change the BASE address and it should work.
