Sorry, you can't just claim relocations like this.  The allocation
process has to be co-ordinated by the ARM EABI, since the numbers you
have used may have been requested by some other third party.  If you are
at the stage where you believe you have proved your model then you
should make a formal request (you can do that via me).
