Change 1722 by scottl@scottl-via-freebsd on 2002/12/04 15:40:08

	aic79xx_pci.c:
		Set the mode correctly for writing to SRAM_BASE in the MEMIO
		test.

Change 1721 by scottl@scottl-junior-freebsd on 2002/12/04 14:49:34

	aic79xx_pci.c:
		Use SRAM and the 0xaa55 pattern for the MEMIO test.
	
	ahd_pci.c:
		Go along with ahc_pci.c and retrieve the allow_memio hint
		from the resource manager and act on it.

Change 1717 by gibbs@scottl-via-freebsd on 2002/12/03 15:29:57

	aic79xx_pci.c:
		Use the TYPEPTR register as a base for our
		memory mapped I/O test.  The Rev B. will allow
		multi-byte access to Scratch Ram, so it is not
		a good test of write-combining or other bad
		behavior.
	
		User CLRPCIINT and CLRSPLTINT in their respective
		handlers.

Change 1714 by scottl@scottl-via-freebsd on 2002/12/02 19:12:42

	aic7xxx_pci.c:
		In the memio test, clear the FAILDIS bit of the SEQCTL
		before running the tests so that PCI errors will be
		flagged.
	
		Write only 4 bytes to the SRAM to prevent VIA chipsets
		from generating a burst transaction on the bus.
	
		Clear the PCIR_STATUS register and restore the SEQCTL
		register before exiting.

	aic79xx.h:
	aic79xx_pci.c:
	aic7xxx.h:
	aic7xxx_pci.c:
		Add a routine for testing memory mapped register access.
		This will hopefully detect things like buggy via chipsets
		so that the OSM can fallback to using I/O mapped access
		when memory mapped I/O simply will not work.

	aic79xx_osm.c:
	aic7xxx_osm.c:
		Remove fallback from the Read Echo Buffer Descriptor
		DV state.  This avoids issues with tape drives that
