0f7f390b49 allow bus-specific lance drivers to use machine-independent buffer/descriptor 
copy functions, and convert isa and pmax drivers to do so.

a comple-time option to support a subset of UFS operations, to build
small bootblocks.

3b8faec21d Initialize pointer to the fb method table. Not initializing the 
method table for the 2100/3100 fb caused a panic when an X server started.

37d37e0791 Change the pmax framebuffer driver to reflect the rcons changes as negotiated 
with pk:
Use dev/rcons/files.rcons in the pmax config file.
Use "rasterconsole" as the tag in pmax/conf, and modify the pmax
framebuffer pseudo-device drivers (fb and rcons) to us rasterconsole.h and
RASTERCONSOLE for compile-time configuration of the rcons pseudo-device.
Modify the pmax rcons pseudo-device driver to initialize a little-endian,
QVSS-compatible font (set its ascent, and set the rconsole structure to
point to that font) before calling rcons_connect().

Tested on a cfb.  The ascent may be wrong (or at least, not be aligned with
the hw cursor sprite) on a 3100.

8945da0c58 Add speed entries for 7200 and multiples. 
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.

ae1b64d888 Fix btoc()/ctob() typo in reading physical memory that stopped ps 
from reading process argument lists.
Allow kernel-virtual memory reads to read the message buffer, since
dmesg needs it.

b543578236 Add a missing "nop" in a delay slot in the floating-point exception 
handler.  Gradual underflow and fp emulation now work correctly.
Proper denorms also fix strtod() inaccuracies and Gcc's "enquire" program.

f28ebc66ca Fix SCC bug that broke getty on pmax SCC lines: if RAW and LITOUT were 
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.

95a27d405b Update pmax kernel to compile with -Werror: 
update MAXINE desktop bus driver to pass a softc to interrupt
handler.  The softc is still statically allocated.

ed4d846a84 Update pmax kernel to compile with -Werror: 
Add prototypes to the driver switch for old-style 4.4bsd/pmax device drivers
(i.e., the old pmax SCSI drivers).

51d59ca152 Update pmax kernel to compile with -Werror: 
Fix the initializer of the prom bootinit() function, to take a char* that's
(presumably) the name of the file  to boot -- even though it's not used.

cd887a9930 Add "kvtophys()", which maps MIPS R2000 kernel-virtual addresses to physical addresses, 
so they can (e.g.) be written to DMA mapping registers.

06bd2712e9 Update pmax kernel to compile with -Werror: 
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.

27361456c5 Force a delay after calling SCC_WRITE_DATA() to give the chip 
registers time to settle. DELAY(2) is reportedly enough.  Without the
delay, output characters are occasionally doubled.

7bb66692c0 Add fine-grain clock code which uses the 25 MHz TURBOChannel bus-cycle 
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.)

version of rconsole.

d1234038d4 Rename the force-all-pending-writes to memory function to wbflush().

entry point.

3589d052f0 Add gory debugging, because I don't have access to a MAXINE to test 
the baseboard framebuffer driver with rcons and it reportedly didn't work.

c8a3bfd5ed Update files.pmax to use Ted Lemon's port of the sparc rcons glass-tty fb 
driver, the "generic" fb pseudo-device driver, and dev/cons.c.
Update an example new-config file (NEWCONF) to use them.

9e925a1b42 Add cdevsw and bdevsw entries for the machine-independent sd and st drivers. 
Add cdevsw and bdevsw entries for the old-pmax tz SCSI tape driver, and
add a do-nothing definition of the requisite tzdump().

d7b9b56e07 Rename the old pmax SCSI driver's "struct scsi_device" to 
"struct pmax_scsi_device", to avoid name conflicts with the sys/dev/scsi
SCSI driver.

a0b0b167c1 Include the new fbio.h, fbvar.h, and lk201.h header files introduced 
with rcons, as dtop.c supplies keyboard and mouse input from the desktop
bus, even though it hasn't itself changed.

b216a24d04 Rename the 4.4bsd/pmax framebuffer glass-tty console structs to 
"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.

6a072ce81d Remove the old cdevsw entries for cfb, mfb, xcfb and pm framebuffers. 
Add an entry for the generic framebuffer "fb" pseudo-device, which
should be used instead of the hardware-specific drivers.
