Add as-yet-unused speed entries for a 1x SCC clock, up to 200 Kbits.
Remove old top-bit-means-delay code, since nothing seems to need it,
and it apparently partially broke lk-201 initialization anyway.
both off, haracters with their top bit clear were interpreted as a delay.
This (strange) behaviour is still available if SCC_PARITY_MEANS_DELAY
is defined.
Update TURBOChannel and ioasic interrupt-establish routines to pass on their
device argument as a "void *", since that's how all the pmax interrupt handlers
are declared.
counter on 5k/240s to interpolate to microsecond-resolution clock
in microtime(). Only the "rev B" ASIC in 5k/240s is known to have
this counter; other models may or may not. This gives microsecond
resolution at user-level, and up to 40ns resolution (modulo the
nominal 5(?) 40MHz cpu cycles for reads to complete) in the kernel.
Change the IOASIC reset function to set up the DMA mapping for the
53c94. Allocate 16 Kbytes of DMA buffer for 53c94 ASCs under an IOASIC,
as the 3MAX baseboard and TC options have 128 Kbytes of static
bounce buffer, and the drivers really _should_ support 16Kbyte
I/O requests. (They don't always.)
Give the LANCE a hard reset on 5k/240s, just to be on the safe side.
(the 5k/240 I use sometimes reported errors at boot time.)
"struct pmax_fbtty". Remove most of its fields, since the fields
in the struct fbinfo render most of them unecessary, and the pmax
now uses rcons anyway. Moe the lk-201 keycode definitions to lk201.h,
so rcons can use them too.
to "kn01_<func>", to avoid confounding a model name (PMAX) with the name of the
entire port (pmax).
Change the signature of interrupt-handlers to take a void *
(a pointer to the softc) and return an int (indicating spurious
interrupts or other conditions.)
Pass softc pointers to the scsi and ethernet kn01 (DS_PMAX) drivers,
rather than having unit numbers wired into the base-level interrupt
handler.

entire port (pmax).
Change the signature of interrupt-handlers to take a void *
(a pointer to the softc) and return an int (indicating spurious
interrupts or other conditions.)
Move consinit() from here to cpu_cons.c.
Eliminate the old old pmax-specific console driver, whcih didn't
know about vnodes. Use sys/dev/cons.c instead.
Delete the old 4.4BSD/pmax TURBOChannel probe routines and ROM-to-driver
name-mapping functions.
"struct pmax_device" to avoid conflict with <sys/device.h>.
Move the glue routines for config.old pmax SCSI device probing from
autoconf.c to conf-glue.c.
old-style pmax polled input for cn_getc(). Needed because the
input side of rcons is not initialized in time for GENERIC kernels
to use it to read a root/swap devicename from /dev/console.
Fix an argument glitch between consinit() and pminit().
Change consinit() to use PROM output for remote consoles, because
the serial drivers aren't yet initializable when consinit() is called.

input side of rcons is not initialized in time for GENERIC kernels
