Update of /cvsroot/src/sys/arch/mac68k/dev
In directory netbsd1:/var/slash-tmp/cvs-serv6126

Modified Files:
        sbc.c 
Log Message:
Due to reliability problems on some models, back out the more radical of
the pc532/dev/ncr.c-inspired changes; in particular, wait for previous
transfer to complete before starting another, as we used to do.  Retain
splbio() protection and simplified sbc_pdma_in().
