Actually OMAP-L138 with newer (d800k008) bootrom revision supports loading from
sd/mmc. Older revision does not supports booting, but its possible to load 2-nd
u-boot stage as in your patch.
This patch does not support loading SPL and 2-nd u-boot stage from different
sources

This patch create copy copy of drivers/mtd/nand/nand_spl_load.c and
drivers/mtd/spi/spi_spl_load.c for the following reasons:
* avoid jump to main u-boot code just after its loading (required
for the next patch: spl - add compressed u-boot image support)
* makes a structure similar to omap3 sources
