Initial support for Marvell Orion5x SoC
This patch adds support for the Marvell Orion5x SoC. It has no use alone, and must be followed by a patch to add Orion5x support for serial, then support for the ED Mini V2, an Orion5x-based product from LaCie. Signed-off-by: Albert Aribaud <albert.aribaud@free.fr>
