split-up spl.c into spl.c, spl_mmc.c and spl_nand.c. This avoids problems with missing defines if a board does not use mmc or nand. This includes adding spl_ prefix to some functions which are now public. spl_image_t is now a public type. Added some of the common functions to omap-common.h Signed-off-by: Simon Schwarz <simonschwarzcor@gmail.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>master
