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 ?
