XScale PXA255 MMU Translation Table Query

- Bcc:
I am using the MPC5 & uE250 examples for a port to our PXA255 platform.
I notice that both tables in hal_mmu_init map the flash from 0 to 0x50000000
& SDRAM from 0xA0000000 to 0 as well as platform specific peripherals to
other addresses.
Why?
Is there a reason for not leaving everything where it's actual address is?
If so is there some documentation discussing this?
Thanks
