Ah, well easy conflict resolution then :)

When I was doing this I was really doubting why it had to be endian
specific, this is mostly a cargo cult from the other stuff that was
already working that way..

I'm personally skeptical any arch could have either EFI stub a
different endianess than the vmlinux, it seems like nonsense on alot
of levels.

So, I will remove the fixed endian pieces from here? Does anyone think
otherwise?

Thanks,
Jason
