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.
Regards,

If you're not using the OF bits, then don't worry about them yet.
They can be added later. of_platform is getting merged with platform
bus anyway, so one driver will work with both.

Again, don't bother with stuff you don't have. It can be added after the fact.
