Memory Mapping


Hi,
I am doing a project, which is poritng eCos on MPC8555 processor and I
am new to eCos. For the porting process I am using MPC8260 as
baseline.

I go through the code in the file "var_regs.h" under
-packages\hal\powerpc\mpc8260\v2_0b1\include. I also read reference
manual which is  MPC8260UM.pdf. I found the some difference in value
stored in the registers .The value in the reference manual is
different from the code. Why this difference?

Now I am trying memory mapping .Please tell me how to proceed, and
please help in my activity.

Thanks and Regards
Dileep Kumar
