Why do you think this change is correct? The PL011 TRM http://infocenter.arm.com/help/topic/com.arm.doc.ddi0183g/I18381.html says the ID registers are at 0xFE0..0xFFC. and for instance on the PBX-A9 devboard: http://infocenter.arm.com/help/topic/com.arm.doc.dui0440b/Bbajihec.html the UARTs are at 0x10009000, 0x1000A000, 0x1000B000, 0x1000C000, so they clearly can't be 0x2000 in size. -- PMM
