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.
