Powerpc question:
Ok, I understand chip select 0 is mapped to 0
upon reset and then it is remapped to something
like 0xfe000000. I understand that SDRAM will
be remapped to 0.   Where does this remapping 
take place (what file or files?)?

How does redboot do this remapping?  Does it execute
out of dual port ram for a while?

I know my answers are dig in the code, but if somebody
could give me a headstart what files to pay
particular attention too, I would appreciate it.
Is there any documentation that talks about
the boot process?
