chuck 442dec5d53 new driver: SCSI for VME147
contributed by: Steve Woodford <steve@mctavish.demon.co.uk>

	this driver is based on the amiga sbic/33C93 driver.   Steve has
	cleaned it up and fixed lots of bugs.    Note that the original driver
	used features which require at least a WD33C93A (the vme147 has the
	original WD33C93 chip <no 'A' suffix>).   Steve has also written
	the DMA routines for the 147 to get things really going.   Hardware
	scatter-gather DMA and sync. SCSI are not supported (yet).   tested
	on several disk drives and a tape drive.   CD-ROM untested, but
	should work.
