I'm currently loading the kernel at a fixed start address using u-boot.
There's no relocation going on.
Accessing anything in the data segment leads to crashes due to file- and
address offsets desyncing.
The patch below fixes this issue and, as a bonus, syncs the code with
the comment.
Possibly affected are armish, beagle, gumstix, palm and zaurus
