omap: add MMC and FAT support to SPL
- Add MMC raw and FAT mode boot support for OMAP - Provide a means by which parameters passed by ROM-code can be saved in u-boot. - Save boot mode related information passed by OMAP4 ROM-code and use it to determine where to load the u-boot from - Assumes that the image has a mkimage header. Gets the payload size and load address from this header. If the header is not detected assume u-boot.bin as payload Signed-off-by: Aneesh V <aneesh@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
