Physical Memory...

I'm writing a scrub module for ECC ram, that simply need to walk
physical ram page by page reading and writing every word in the page.

Question is: From a module, what does the memory address space look
like? Where is physical ram located? Is it mapped at address 0 up? or
from 0xC0000000 up? or where?

To date I've assumed page one is located at 0x400, but I'm not
terribly confident that this is correct.
