Update of /cvsroot/src/sys/dev/tc
In directory netbsd1:/var/slash-tmp/cvs-serv1824

Modified Files:
        asc.c asc_ioasic.c asc_tc.c ascvar.h 
Log Message:
Use direct DMA with the IOASIC ASC SCSI interface.  DMA buffering can be
re-enabled with ASC_IOASIC_BOUNCE.
All DMA buffered processing is now done in the bus-specific DMA routines
in asc_ioasic.c and asc_tc.c.
Disable several informational messages dealing with non-empty FIFO conditions,
but allow enabling with ASC_DIAGNOSTIC for troubleshooting.
