The boards I have ported use the memory layout which is documented in
the README. Unfortunately, due to historical reasons the old ARMboot
code uses another scheme and nobody had the time to fix this "the right
way".

My -ptx patches have a hack for this, but I agree with Wolfgang that
somebody should fix it correctly instead of applying workarounds...
