only a small piece of ROM...

here is my internal memory mapping:

start        size      type
-----------------------------
0x1fc00000 - 128Ko    - ROM
0x01000000 - 128Ko   - FLASH

At boot time ROM code do some init and then jump
into the internal flash mem.

I think there's no possibilities to run linux except
in KSEG2 and KSEG3...Do you think it's possible ?

By the way why Linux memory management need to care
about physical addresses ?

Francis.
