boot.c: update from sun3 port, with changes for my new boot code put in.
conf.c: config from openbsd, by Theo de Raadt
dev_net.c: update from openbsd (standard dev_net with changes from theo)
dev_net.h: proto from openbsd
exec_mvme.c: from sun3 port, adapted by me. I also fixed a bug that
prevented ZMAGIC kernels from running.
libsa.h: new file by me
parse_args.c: by Theo de Raadt from OpenBSD with slight revisions from by me
to make it fit the new format.
naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.
Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_start)()
to take a struct ifnet *, rather than a unit number.
disklabel.h: new disklabel format (from Dale Rahn)
param.h: new delay stuff (from sun3 port)
vmparam.h: nuke eiomap for new autoconfig (from jason)
z8530var.h: for MI driver (from jason)
- new autoconfig scheme+vme (autoconf.c,clock.c,clockreg.h,
clockvar.h,vm_machdep.c)
- new interrupt scheme (isr.c,isr.h,locore.s,machdep.c,vectors.s)
- switch to MI zs driver (conf.c)
- new disklabel code, from Dale Rahn <drahn@pacific.urbana.mcd.mot.com>
(disksubr.c, compatable with theo and dale's openbsd version)
- new delay() based on sun3 port, using dynamic configuration from
the sparc port (intergrated by me), calibration moved to startup
by jason. (locore.s,machdep.c)
- clean up: nuke eio space (genassym.c,locore.s,pmap.c,pmap_bootstrap.c),
nuke STACKCHECK (locore.s), prevent maxuser overflow (pmap.c),

fixes the following problems:
- Timeout on START/STOP unit command (ie. when spinning up the drive)
Side effect of this fix is to reduce the busy-wait time in CMD phase.
- Occasionally, the driver would lose an SBIC interrupt, especially when
a tape drive was re-selecting on a busy SCSI bus.

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.
remove their 'integrate' (usually defined to be 'static') keywords.
when lance drivers are split up by attachment, more than one file will
reference the copy/zero functions (i.e. not just the file that pulls in
am7990.c... and eventually inclusion of am7990.c should go away entirely).
- 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.
execpt without quotes. meant to be __CONCAT()ted for easy #includes
of machine-dependent headers for MI code (e.g. for the MI ISA/EISA/PCI/TC
bus code).
