- Add a driver for the Enhanced Direct Memory Access controller found
in the AM335x SoC. Written by Jared D. McNeill, with some final debug by me.
- Supports only DMA (not QDMA) yet, and there's no support for DMA event
matrix yet (this means that only primary DMA events can be used)
- Add support for DMA transfers. From Jared D. McNeill, with final debug by
me. With this I can get nearly 20MB/s from my sdcard on the BB black at 1Ghz
(not bad for a 50Mhz 4-bits bus), and still 15MB/s on the BB white at
low speed (275Mhz).
- Add the edma controller, and enable DMA for sdhc0 and sdhc1
