tested by flxd@

Add new USB-enabled kernel config(s) based upon GENERIC for pmax, include it as kernel set in the build and make it a choice in sysinst.
OK simonb@

Bless pmax with USB device files/majors and make kernel configs with USB and typical drivers work.

Since files.wscons et al. are included by ~all ports anyway, include
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.

Provide assembly versions of the clock timing calculation loops that
aren't effected by changes in compiler optimisation.

Fixes PR port-mips/26959 from Izumi Tsutsui

Add drivers for the desktop bus, DC-7085 and pm display. Make it possible to
select between rcons or wscons at compile time. Ok'ed by simonb.

Remove nonexistent arch/pmax/pmax/mcclock.c. (pmax uses dev/dec/mcclock.c)

Since everyone uses clock_subr.c (or should, if they don't currently),
list it in conf/files instead of in every port's files.*.

branches: 1.104.2;
Switch to use mips/softintr.c for softintr(9).

now that mem_no is emitted by config(8), there is no reason to keep
copy of more or less identical iskmemdev() for every arch; move the function
to spec_vnop.c, and g/c machine-dependant copies

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

branches: 1.101.2;
Don't make arch/mips/mips/mips_mcclock.c mandatory for all mips ports
with an mcclock - pmax is the only one currently using this.

branches: 1.100.2;
All the mips ports had an identical procfs_machdep.c, so use a common
file under arch/mips/mips.

- convert usage of "defopt" to "defflag" where the relevant option does
not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to
defparam recently.
- minor whitespace & formatting cleanups

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""

branches: 1.97.4;
Move pmax-only if_le_ibus.c from dev/tc to arch/pmax/ibus.

Move asc_tc and asc_tcds config info to dev/tc/files.tc now that pmax
uses MI SCSI.

sii does not require ncr53c9x.

branches: 1.94.2;
Switch to MI SCSI and drop old pmax MD SCSI support completely.

NetBSD/pmax now has GENERIC_SOFT_INTERRUPTS.

branches: 1.92.4;
Add machdep file for procfs. Currently only used for linux-style
/proc/cpuinfo (only active when procfs is mounted with -o linux).
For ports other than the i386 this currently produces an empty
string.

We haven't used the 4.4BSD kadb stuff for a long time; garbage
collect it.

the tcds cards work in pmaxen. move tcds attachment to files.tc. leave asc
at tcds in files.alpha for now, and add a new `xasc at tcds' to files.pmax.
after pmax has moved fully to MI scsi (and `asc' is MI scsi), we should move
the device asc, etc., lines to files.tc.

- Nuke xasc_ioasic.h and xasc_pmaz.h as no code uses the symbols they define.
- Hide #include <pmax/dev/device.h> for "pmax oldscsi" inside
#if NRZ > 0 || NTZ > 0.

Switch to sys/dev/md_root.c.

px requires rasops8 to compile

Allow sii driver to be compiled with MI SCSI support. Now DS3100 users
can use MI SCSI!

branches: 1.85.2;
Allow non-pmax to use COMPAT_ULTRIX.

Add the RAIDframe device major to the machine-dependent config files
so that the right entries get added to dev_name2blk[]. Needed for / on RAID.
(Whoops! I missed checking these in when adding the RAID_AUTOCONFIG stuff.)

NLE_PMAX symbol in le_pmax.h has gone.

Introduce MI SCSI codes; for DECstation 5000s only this moment.
Disabled by default and needs arrangements in conf file to use it.
See DS5000 as a sample.

Revert the removal 'include "dev/scsipi/files.scsipi"' directive; it's
neccessary to make pmax/conf.c compiled correctly.

Group and reorder old SCSI driver descriptions into a single
location. Nuke files.scsipi inclusion which has never been useful.

Massive change of console initialization to make WSCONS transition easier.

s/4(..)bsd/4$1BSD/

Oops, back out some test 5500 stuff from previous commit - only RAMDISK
was meant to be changed.

We now need a 3MB miniroot.

Replace old asic.c with one imported from a development branch.

callvec.c has moved from stand/lib to stand/common.

XXX: The kernel proper shouldn't rely on files in stand! Will fix soon.

Some fix on comment descriptions.

Add an `addr' locator to the `ibus' bus. This allows you to wire down
unti numbers on systems which have e.g. multiple `dc' devices on the
internal bus (like the 5100).

Resolve 3max IOASIC disguise; round #2.

Very large scale change to sweep obstracles to remove 3MAX IOASIC disguise.
- Rework ibus device configuration and interrupt handler assignment.
- Remove TC device exposure in 'mainbus.c'
- Squash 'ibus_{3100,5100}.c' into a file; it can not cope with 3max.
- 'struct confargs' -> 'struct mainbus_attach_args'
Now about to remove tc_slot_info[] and tc_enable_interrupt inherited from
4.4BSD.

pseudo-device -> defpseudo, per grammar change in config(8).

px.c requires that qvss_compat.c be compiled in.

Only declare block major numbers for devices which can be the root device.

- Track filename changes.

- Have 'promcall.c' for various utilities by PROM calls.
- Adjust files.pmax.

`pm' device can also be 8bpp - fix dependancy line.

Fixed to match rasops config glue.

Add configuration glue needed by rasops, wsfont, rcons and the px driver.

Remove trailing white-space.

callvec.c moved in stand again...

A 5800 is a kn5800.

White space and comment formatting police

Use common date conversion functions - not runtime efficient, but
brain-efficient...

adapt to LANCE driver split

Complete from-scratch rewrite of the DECstation bus.h, brining it
up-to-date with the current API, and implementing preliminary
support for bus_dma.

Rework pmax kernel config:
* ibus (virtual bus for baseboard direct-attach deviecs)
* 5100 support, using ibus
* rename "clock" to mcclock for future support of Qbus machiens
* use sys/dev/dec mcclock_pad32 machinery for pmax mcclock
* reworked TC config code.

Split 3max (kn02) and 3maxplus (kn03, kn05) memory-error handling out
dec_3max.c into a shared file. These models have compatible memory
subsystems, the same memory slots, and (apparently) the same error reporting.

Add markers for where MNN probes for configurations with a mixture of
RAM sizes and for Prestoserve NVRAM (in normal RAM slots) should go.

Update config files after splitting model support.

Update GENERIC and R4000 configs after splitting model-speciifc support.

Remove "class" declarations, and add "devclass" declarations where
appropriate. Fix several inconsistencies between device class and
attributes. Mostly from Chris Demetriou.

Update for changes to config.

Merge scsipi branch in the mainline. This add support for ATAPI devices
(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.

branches: 1.46.2;
Create sys/dev/dec and cleanup sys/dev/tc:

* Move clockvar.h (header file for generic clock code) to sys/dev/dec.
* Move if_le_dec.c with DEC padded LANCE-dma (pmax/pmax, ioasic, vax 3400)
to sys/dev/dec. Remove from sys/dev/tc.
* Declare attribute le_dec_subr in /sys/dev/dec/files.dec,
use if_le_dec.c when it's defined.
* Move IOCTL asic declaration from pmax and Alpha MD machine
files to sys/dev/tc/files.tc.
* move TurboChannel and ioasic if_le attachments from pmax and Alpha machine
config files to /sys/dev/tc/files.tc. Add le_dec_subr attribute.
* Add if_le_dec attribute to if_le_ibus (pmax ds3100 pmax) LANCE attachment.

Partly merged back with Alpha code by Jonathan Stone. Needs more merging.

Use generic MIPS pmap vm_machdep.c

Move the mips sys_machdep.c from pmax/pmax to mips/mips, to enforce a
common sysarch on all mips ports.

Include pm_ds.c if pm_ds, not dc_ds - dc_ds gets set for the 5000/200 as
well as the 3100, but trying to include pm_ds.c for a 5000/200-only
configuration fails.

Add 'needs-flag' to pmax, 3max dc (DZ-11 clone) front-ends (dc_ds, dc_ioasic
respectively), so console setup code can test forconfiguration of the
correct front-end (via NDC_DC and NDC_IOASIC, respectively).

Delete 'needs-flags' from dc.c. GC obsolete uses of NDC, "dc.h".

Change `needs-count' on scc to `needs-flag': should have been `needs-flag'
since rev 1.18 of pmax/tc/scc.c.

Add `offset' locator to ioasic-attached devices, for compatibility with
the ioasic_submatch() used in drivers shared by pmax and alpha ports.

Fix up includes so that up-to-date versions of 'config' can be used
to config pmax kernels. Not all kernels can actually be config'd because
of device declaration problems, but i don't know how to fix those.

Change pmax port over to using ``mips MI'' trap handler.

Comment out config lines for MI scsi drivers, to make it absolutely clear
we don't yet support them.

The dc has to have needs-flag so dc.h gets generated.

Add files.pmax entries for separate cfattach front-end and ``MI'' backend
drivers:
pm - pmin/pmax d503 PCC + BrookTree 478 framebuffer
dc - dc7085 DZ-11 clone
asc - ioasic and TurboChannel SCSI option card 53c94 SCSI-2
sii - DEC scsi ASIC used in pmin/pmax, 5100, and Firefox vaxes

Use the MI LANCE drivers - the pmax-specific one no longer compiles.

branches: 1.31.4;
Make the MI LANCE driver standalone, and use cfattach to resolve
naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.

Remove files moved to mips/mips; they are included in mips/conf/files.mips.
Add the pmax-specific portion of trap handler, pmax/pmax_trap.c, which
was split off from pmax/trap.c.

adjust to deal with expression support for optional file specs

fix typo in recent attachment changes: (interface) attributes for asc
specified twice.

New device attachment scheme:

- 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.

Propagate changes from cfb driver to not require "needs-count" to other
pmax framebuffer drivers.

Add dev/tc/asc.c to files.pmax, until the merger of Alpha and pmax TC drivers
s completed.

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.

Use `files.ultrix'

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.

Change pmax (asc and sii) SCSI drivers to use "needs-flag", as the
drivers have been fixed to not require "needs-count".

Add back the lines for the "rcons" console driver, even though it's
not merged into the pmax port yet, as conf.h was patched to include
"rcons.h". Adding the device here, but not configuring it (e.g., in
GENERIC) keeps conf.c happy until rcons code is merged.

Rename "asic" to "ioasic", to be compatible with "machine-independent"
turbochannel/asic device drivers. (also comment out tt.c.)

Un-comment dependency on file cpu.c, since cpu.c has been commited to CVS.

Fix cut-and-paste error in device order (clock).

Snapshot of a prototuype for a new-config GENERIC configuration.
This relies on an ugly mixture of new-style config and old-style config.

resurrect, and move files.pmax.newconf to new location.
