The Armada 370/XP SoC family has a completely configurable address space handled by the MBus controller. This patch introduces the device tree layout of MBus, making the 'soc' node as mbus-compatible. Since every peripheral/controller is a child of this 'soc' node, this makes all of them sit behind the mbus, thus describing the hardware accurately. A translation entry has been added for the internal-regs mapping. This can't be done in the common armada-370-xp.dtsi because A370 and AXP have different addressing width.
