Because uboot's bootm does not handling the relocation?

That would make more sense (This was my understanding as well, 
actually), but we're still having an issue: The uImage header, stored in 
RAM, has a load address that is wrong for some platforms.  Unless we're 
going to change that with an in-uboot memory editor, bootm will honor 
the address in that header and the boot will fail.
