    [ARM] 4143/1: AT91: Prepare for AT91SAM9263 support · d0760b3b
    Andrew Victor 提交于
    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.
