Do you admit that the first branch of the if I changed asserts the
header to start at ih_load and the other asserts the data to start at
ih_load?  So if you have an XIP image in RAM starting at a wrong
address, booting will fail.

So in my eyes the correct fix is to take the patch I sent + fix Linux
not to skip the header.

BTW: I couldn't find this config item "Make a XIP (eXecute in Place)
kernel", neither in Linus nor in your tree:

	zeisberg at cassiopeia:~/gsrc/linux-2.6$ for tree in denx linus; do git describe remotes/$tree/master; git grep "Make a XIP" remotes/$tree/master; done
	v2.6.21-rc3-582-gb0dd6c9
	v2.6.21-rc3-276-gbaab108

And even

	git branch -r | grep denx | xargs git grep "Make a XIP"

didn't return anything.

Best regards
Uwe
