For OMAP we find this run-time by loading u-boot.img instead of
u-boot.bin. u-boot.img has a 64 byte header with all necessary
information such as size, load address, image type etc. The OMAP SPL
can in fact load any image that has a standard u-boot header(mkimage
header), including a uImage. This scheme was suggested by Wolfgang.
