[U-Boot] Craneboard with Uboot and xloader

[Mohamed HAMZAOUI]

I tried following your instruction and i have been found the file MLO and
u-boot.img in the build/uboot directory but when i use them with the
generated rootfs th craneboard boot from the nand and not from my SD
although it's configured to booting from SD card and i tested it whith a
openembedded distribution.
the first log for starting is :
