Subject: armv7: fix relocation skip
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=b9c5081d7d6ebc3290813675ca8771f4471edb85;p=u-boot.git

armv7: fix relocation skip

I doubt the stack_setup() was defective before:
 we load the current location of _start and compare against destination
 of relocate_code(). If we are already there we shoud skip the
 relocation and jump over to clear_bss. Before the clear_bss was also skipped.
