I just realized that the byte patterns above matches
exactly what my vmlinux ELF image. Here is the hex
dump:

00000000  7f 45 4c 46  01 02 01 00  00 00 00 00  00 00 00 00

So, u-boot appears to have extracted the image correctly
and relocated it to address 0, but I'm thinking I probably
need to install a pure binary instead of an ELF image?
Does u-boot understand ELF or does it only expect a pure
binary?

Thanks again!
