The error started here. It is able to detect fdt from fit header but not
able to read it from file. If you don't mind can you tell me what is the
size of the file u-boot.img?

A dumb question: Can you confirm that on this same HEAD the RFC patch
from you works fine?

I verified this on 2 different platforms and worked fine. Lets see If I
am missing any corner case.

Thanks and regards,
