Subject: [PATCH 01/18] 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.
+
+- clocks : Should be phandle to a clock.
+
+Example:
+
+ timer@2c000600 {
+ compatible = "arm,cortex-a9-global-timer";
+ reg = <0x2c000600 0x20>;
+ interrupts = <1 13 0xf01>;

bcm53xx: initial support for the BCM5301/BCM470X SoC
with ARM CPU
This patch adds support for the BCM5301/BCM470X SoCs with an ARM CPU.
Currently just booting to a shell is working and nothing else, no
Ethernet, wifi, flash, ...

These are some hackish patches to make the Ethernet driver work somehow
on this arm core.
The flash driver is not working, so we removed the nvram reading, this
should be changed after we have a flash driver.
The mdelay(1) is a ugly workaround for this arm chip, this seams to be a dma problem.
The PHY says it is not connected by default, just ignore it.
