bcm53xx: add initial support for ARM based BCM47XX and BCM53XX SoCs
This was only tested on a Netgear R6250, but it could also work on other devices when the correct images are generated. It is only possible to boot into a ram disk, no Ethernet, Wifi, flash, USB is supported. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 37268

+Subject: [PATCH 01/17] clocksource:arm_global_timer: Add ARM global timer
+ support.
+
+This is a simple driver for the global timer module found in the Cortex
+A9-MP cores from revision r1p0 onwards. This should be able to perform
+the functions of the system timer and the local timer in an SMP system.
+
+The global timer has the following features:
+ The global timer is a 64-bit incrementing counter with an
+auto-incrementing feature. It continues incrementing after sending
+interrupts. The global timer is memory mapped in the private memory
+region.
+ The global timer is accessible to all Cortex-A9 processors in the
+cluster. Each Cortex-A9 processor has a private 64-bit comparator that
+is used to assert a private interrupt when the global timer has reached
+the comparator value. All the Cortex-A9 processors in a design use the
+banked ID, ID27, for this interrupt. ID27 is sent to the Interrupt
+Controller as a Private Peripheral Interrupt. The global timer is
+clocked by PERIPHCLK.

++* ARM Global Timer
++ Cortex-A9 are often associated with a per-core Global timer.
++
++** Timer node required properties:
++
++- compatible : Should be "arm,cortex-a9-global-timer"
++ Driver supports versions r2p0 and above.
++
++- interrupts : One interrupt to each core
++
++- reg : Specify the base address and the size of the GT timer
++ register window.
++
++Example:
++
++ timer@2c000600 {
++ compatible = "arm,cortex-a9-global-timer";
++ reg = <0x2c000600 0x20>;
++ interrupts = <1 13 0xf01>;
