[PATCH] ARM: mvebu: add Device Tree for the Armada 385 RD board

[Gregory CLEMENT]

The Armada 385 RD board is the reference design board from Marvell
for the Armada 385 SoC. This commit adds a Device Tree description for
this board, which enables the following features:

 * Network interfaces
 * I2C bus
 * Serial port
 * SPI bus, with a SPI flash
 * PCIe interface

Hi,

I have received this board only recently, so that why its device tree
comes only now. This patch should not cause any trouble to other part
of the kernel, so that's why I think it is reasonable to have it in
3.15.

Thanks,

Gregory
