[PATCH 0/4] dmaengine: Add driver for Xilinx MPMC

["Steven J. Magnani" <steve@digidescorp.com>]

This is a DMA engine driver for SDMA channels on a Xilinx Multi-Port
Memory Controller (MPMC). 

Caveats:
* The OF bus driver (part 4) is based on the fsldma driver and how I
  thought the device and channels might be represented in a device tree blob.
  As I don't use OF in my kernel, all I am able to do is verify that the code
  compiles. Suggestions for improvement are especially welcome here.

* Similarly, I took a stab at DCR support based on the ll_temac driver
  and some discussions about supporting both DCR and simple pointer access
  to device registers. I'm working on Microblaze so cannot test the DCR code.
