[PATCH 0/2] ARM: vexpress: DT enablement

[Lorenzo Pieralisi]

This patchset enables basic Versatile Express DT support in the Linaro kernel.

It applies to:

git://git.linaro.org/kernel/linux-linaro-2.6.38.git master

	commit 7c4bc9c2662c6d9840afed0e29eb01314af9bb78

It defines the required match table and adds a simple dts file where the memory 
node by default declares the full 1GB memory space.

Tested on a Versatile Express board with u-boot compiled with DT support.

[PATCH 1/2] ARM: vexpress: add basic DT platform matching support

[Lorenzo Pieralisi]

This patch adds a DT match table to the Versatile Express machine
description in order to enable basic device tree support.

Tested on a Versatile Express board where the device tree blob is
passed to the kernel by u-boot.

[PATCH 2/2] ARM: vexpress: add basic dts DT source

[Lorenzo Pieralisi]

This patch provides a simple device tree source for the Versatile
Express board. It just defines memory layout and assigns a compatible string
to the board.

Compiled blob tested on Versatile Express, passed to the kernel
through u-boot. 'chosen' node defined within u-boot to avoid cluttering
the default dts configuration.

Merged into devicetree/test & devicetree/arm.  I squashed this with
the second patch while I was at it.  I see that Nicolas has already
picked it up into the Linaro tree, so I don't need to worry about
pushing it to him.  :-)
