Prabhakar Kushwaha d2ae2e20fb driver/memory:Move Freescale IFC driver to a common driver
Freescale IFC controller has been used for mpc8xxx. It will be used
 for ARM-based SoC as well. This patch moves the driver to driver/memory
 and fix the header file includes.

  Also remove module_platform_driver() and  instead call
  platform_driver_register() from subsys_initcall() to make sure this module
  has been loaded before MTD partition parsing starts.

Ezequiel Garcia 3edad321b1 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.

Aneesh V 6bc9c66e56 Documentation: dt: emif: device tree bindings for TI's EMIF sdram controller
EMIF - External Memory Interface - is an SDRAM controller used in
TI SoCs. EMIF supports, based on the IP revision, one or more of
DDR2/DDR3/LPDDR2 protocols. This binding describes a given instance
of the EMIF IP and memory parts attached to it.
