1998-01-20Merge bus_dma support from NetBSD, mostly by Jason Thorpe. Only i386 uses itNiklas Hallqvist
so far, the other archs gets placeholders for now. I wrote a compatibility layer for OpenBSD's old isadma code so we can still use our old driver sources. They will however get changed to native bus_dma use, on a case by case basis. Oh yes, I almost forgot, I kept our notion of isadma being a device so DMA-less ISA-busses still work
