Is there a possibility that your download from u-boot.realsimulation.com is not actually corrupted? I have downloaded several files from that site and THOUGHT they were corrupted until I came across this old post by Gizzmoe:

Apparently some of the files on that site are missing a header byte. I applied Gizzmoe's fix and they worked fine after that. Just a thought.
