Arnd, Olof,

You'll find in this patch set the initial support for a new family of
ARMv7-compatible Marvell SoCs, that we have choosen to support in the
arch/arm/mach-armada/ directory.

At the moment, both the Armada 370 and the Armada XP SoCs are
supported in this directory, and we are able to build a single kernel
image that boots on both SoCs. Both SoCs use the PJ4B processor, a
Marvell-developed ARM core that implements the ARMv7 instruction
set. We are currently using Marvell evaluation boards for both of
those SoCs, and the support for those boards is added in this patch
set.

This preliminary support only includes the necessary code for timer
and IRQ support, the serial controller is a standard 16550-compatible
one. The diffstat looks like:

Hi Thomas

Is mach-armada a good idea? What are many different armada chipsets families:

Armada 100, 300, 500, 600, 1000, 15000, XP. 

You only seem to support 300 and XP. Where would the others go? 300 is
actually mach-dove, etc.
