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),

of a lot of instability problems on the Falcon. I also enabled DMA on
interrupt basis for the Falcon.
- Try to handle targets that request too much data more sanely.
- Some fixups for strict prototypes + -Wall
Thanks to Markus Kilbinger for providing the debugging support.
- Disable interrupt-driven PDMA when writing (use polled PDMA instead).
- Be more careful about when to flag a transfer as completed.
The result of these changes is that interrupt-driven PDMA works well
enough to bring the system up.
bus-independent core driver. Tested on all three bus types, including
an isa 3c509 masquerading as an eisa device (use ep* at eisa? slot ? in
your kernel config file to catch this one).
XXX Driver still needs to be converted to <machine/bus.h>
Argh, why is a fuction from the RetinaZ2 console driver in the console
driver for the RetinaZ3 ? Fixed.
Fixed some warnings from -Wall if you don't use -DDEBUG
allow any baudrate the hardware allows, and to forbid two baudrates
(50 and 75) which the hardware does NOT support but which the old
speed conversion table pretended to support.
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.
