(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.
Use definitions from this file for match_podule() rather than hardcoded
values.
Added a routine asc_minphys() in preparation for driver changes when on
card DMA support is added.
multi-channel driver), or to SCSI_CHANNEL_ONLY_ONE if a
single-channel driver.
(2) use scsiprint() rather than a locally-defined autoconfig print
function, and kill any locally-defined print function.
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
chained podule interrupt handlers.
Fill out the ih_maskaddr and ih_maskbits fields in the interrupt handler
structure so that interrupt dispatcher knows where to look to determine
if the handler should be called.
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
