This adds ARM gic interrupt controller initialization using device tree
data.
The initialization function is intended to be called by of_irq_init
function like this:
const static struct of_device_id irq_match[] = {
{ .compatible = "arm,cortex-a9-gic", .data = gic_of_init, },
{}
};
static void __init init_irqs(void)
{
of_irq_init(irq_match);
}

Following the discussion here:
http://lists.ozlabs.org/pipermail/devicetree-discuss/2011-August/007301.html
The L2x0 L2 Cache Controllers support a combined interrupt line
which can be used for several events (e.g. read/write/parity errors on
tag/data RAM, event counter increment/overflow). Unfortunately the
OF binding added in c519ecf2 ("ARM: 7009/1: l2x0: Add OF based
initialization") does not represent the interrupt.
This patch adds an "interrupts" property to the L2x0 OF binding,
representing the combined interrupt line.

This adds probing for ARM L2x0 cache controllers via device tree. Support

This patch adds support for picoXcell boards to be booted using the
device tree registering the VIC's, UART's and timers.
v3: - fixup vic compatible string in binding
v2: - cleanup empty mach headers
- convert to of_platform_populate()
- simplify uncompress.h

For testing the dt work, define a dt-enabled versatile platform.
This patch adds a new versatile platform for when using the device
tree. Add platform and amba devices are discovered and registered by
parsing the device tree. Clocks and initial io mappings are still
configured statically.
This patch still depends on some static platform_data for a few devices
which is passed via the auxdata structure to of_platform_populate(),
but it is a viable starting point until the drivers can get all
configuration data out of the device tree.

SiRFprimaII is the latest generation application processor from CSR’s
Multifunction SoC product family. Designed around an ARM cortex A9 core,
high-speed memory bus, advanced 3D accelerator and full-HD multi-format
video decoder, SiRFprimaII is able to meet the needs of complicated
applications for modern multifunction devices that require heavy concurrent
applications and fluid user experience. Integrated with GPS baseband,
analog and PMU, this new platform is designed to provide a cost effective
solution for Automotive and Consumer markets.
This patch adds the basic support for this SoC and EVB board based on device
tree. It is following the ZYNQ of Xilinx in some degree.

This modification sets the PMU hardware type based on data embedded in the
binding, allowing easy addition of new PMU types in future.
Support for new PMU types not provided by devicetree can be added later using
platform_device_id tables in a similar fashion.

Add a function to create amba_devices (i.e. primecell peripherals)
from device tree nodes. The device tree scanning is done by the
of_platform_populate() function which can call of_amba_device_create
based on a match table entry.
Nodes with a "arm,primecell-periphid" property can override the h/w
peripheral id value.

The 1st board support is minimal to get a system up and running
on the Xilinx platform.
This platform reuses the clock implementation from plat-versatile, and
it depends entirely on CONFIG_OF support. There is only one board
support file which obtains all device information from a device tree
dtb file which is passed to the kernel at boot time.
