The Atmel AT91SAM9263 processor includes many more integrated
peripherals than Atmel's previous ARM9-based AT91 processors, so this
has necessitated a few changes to the core AT91 support.
These changes are:
* The system peripheral I/O region we remap has increased from
0xFFFA0000..0xFFFFFFFF to 0xFFF78000..0xFFFFFFFF.
* The increased I/O region forces changes to entry-macro.S and
debug-macro.S due to ARM's limited immediate offset addressing
modes.
* Maximum number of GPIO banks increases to 5.
* 2 MMC controllers so the board-setup code needs to specify which
controller it wishes to use when calling at91_add_device_mmc().
Original patch from Nicolas Ferre.
