Tune xDMA interface slightly:
o Move descriptors allocation to DMA engine driver
o Add generic xdma_request() routine
o Add less-generic scatter-gather application based on xdma interface
Typical op
Tune xDMA interface slightly:
o Move descriptors allocation to DMA engine driver
o Add generic xdma_request() routine
o Add less-generic scatter-gather application based on xdma interface
Typical operation flow in peripheral device driver is:
1. Get xDMA controller
sc->xdma_tx = xdma_ofw_get(sc->dev, "tx");
2. Allocate virtual channel
sc->xchan_tx = xdma_channel_alloc(sc->xdma_tx, caps);
3. Setup transfer status callback
xdma_setup_intr(sc->xchan_tx, my_tx_intr, sc, &sc->ih_tx);
4. Request a transfer(s)
ret = xdma_request(sc->xchan_tx, &req);
5. Free the channel
xdma_channel_free(sc->xdma_tx);
6. Free the controller
xdma_put(sc->xdma_tx);

Add xDMA -- the DMA abstraction layer, initial verison.
xDMA is a DMA framework designed to abstract the interaction
between device drivers and DMA engines.
