75ac5055c8 Add the edma controller, and enable DMA for sdhc0 and sdhc1 2015-04-14 18:45:57 +00:00

9fe03010cf 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).

529684c049 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)

1478a901ec Add a new SDHC_FLAG, SDHC_FLAG_EXTDMA_DMAEN, which request that the 
SDHC_DMA_ENABLE bit be set in the command, even if we're using an
external DMA engine. Needed by the upcoming DMA support for AM335x
(beaglebone).

8ded945441 Centralize bookkeeping of rnd_initial_entropy. 
It is not adjusted everywhere it should be, although the only places
it perhaps formally ought to be are places with questionable entropy
estimates in the first place.

e1cf58ac37 Sync ixg(4) up to FreeBSD r243716: 
- A lot of bugfixes. Some of them are realted to multi queue and those
   have not affected in NetBSD because we have not used it yet.
 - Show 1000Base-SX correctly.
 - Fix if_baudrate from 1G to 10G.
 - Improve performance.
