I just noticed that you use CONFIG_OF_EMBED. Is this just for
debugging? It should not be used for normal operation.
>From README.fdt-control:
"If CONFIG_OF_EMBED is defined, then it will be picked up and built into
the U-Boot image (including u-boot.bin). This is suitable for debugging
and development only and is not recommended for production devices."
