drivers: memory: Introduce Marvell EBU Device Bus driver
Marvell EBU SoCs such as Armada 370/XP, Orion5x (88f5xxx) and Discovery (mv78xx0) supports a Device Bus controller to access several kinds of memories and I/O devices (NOR, NAND, SRAM, FPGA). This commit adds a driver to handle this controller. So far only Armada 370, Armada XP and Discovery SoCs are supported. The driver must be registered through a device tree node; as explained in the binding document. For each child node in the device tree, this driver will: * set timing parameters * register a child device * setup an address decoding window, using the mbus driver Keep in mind the address decoding window setup is only a temporary hack. This code will be removed from this devbus driver as soon as a proper device tree binding for the mbus driver is added.
