Tobias can try CONFIG_SKIP_RELOCATE_UBOOT, but it isn't likely to work 
as is.  That flag is to configure u-boot to be loaded directly into RAM 
and run out of RAM (i.e. no relocation from flash to RAM).  U-Boot was 
not designed to run from flash (aka. XIP - eXecute In Place) and nobody 
has done that as far as I know.

That doesn't mean u-boot cannot run XIP, it means that it will take an 
unknown amount of effort to make it happen.
