We cannot tell you. It is you who defines the memory map of your board.

These are the address masks used in the MPC8xx memory controller.

You will want to read the section about the memory controller in  the
MPC8xx User's manual.

Sorry, this doesn't help anything. We  would  need  _all_  the  nasty
little  details (probably including the schematics), and then it will
become real effort, which you cannot get for free, not even here.
