make it possible to use hpcboot on HPC devices with broken touch

a focused control).
instructions so that prologue code and function code get mixed, and
you get a lot of noice from this printf, making traceback very hard to
read if not useless.
to only call pckbc_machdep_cnattach() if this is present. This allows
pckbc_machdep_cnattach() to be omitted entirely on most ports, where it only
returns ENXIO anyway.
The devices with this attribute at the moment are pc(4) on i386 and bebox, and
pckbc on sparc, where pckbc_machdep_cnattach() mysteriously returns 0 rather
than ENXIO.
lcd driver can be configured with or without wsdisplay.
With wsdisplay, it supports text mode using rasops in 8bpp or 16bpp.
Without it, users only can mmap(2) the framebuffer.
XXX: 1-, 2-, 4-, or 24- bpp mode is not supported yet.
XXX: S3C24x0's LCD controller can have virtual screen which is bigger
than actual LCD panel. Our wsdisplay framework doesn't have
features to utilize it.
interrupts; some boards actually use those GPIO pins as external
interrupt sources.
Instead, assign soft interrupt bits to on-chip sources which are
not used by the IXP425 port.

itself as a random exception with RedBoot just after 'go'.
Fix it by adding a data-dependency on the 'ldr' result.

and remove the code in pckbc_machdep_cnattach() that was conditional on its

pckbc_cnattach() will call pckbd_cnattach() itself if necessary).

* detect and store vc2 revision. This is (likely) the important factor in
determining the proper cursor offset, so add a bit of logic that does the
right thing on my revision 0 vc2. This will have to be determined
empirically, revision by revision.
* take a stab at detecting framebuffer depth. SGI does it quite differently,
but their algorithm doesn't work, so we'll do it along the same lines as
linux.
* implement newport_mmap() for use by X. The necessary xsrc commits have been
made (with the notable exception of the config/cf changes, which probably
shouldn't go in until 4.4.0 has been imported).
Added software volume control functionality in vraiu_volume(), called from
vraiu_start(). Can be changed by the mixerctl 'inputs.dac' -- 0 is muted,
255 is the level that the driver previously outputted (quite loud on the
IBM Workpad Z50), and everything else is a smooth transition between the
two. Thanks to toddpw@ for lending me the hardware to test these changes.
the recently introduced files.ppbus.
Also, let the mvme68k port use it's own lpt implementation for now,
so define USE_ALT_LPT option in std.memv68k.
This makes the mvme68k kernels configure and build again.

It effectively removes the now redundant reference to "beep.h" and removes
an associated prototype that wasn't used.

NB: While acceptable as a temporary workaround since most (all?) Cobalt
hardware comes with no less than 16Megs on board, changing a kernel load
address or making a boot loader relocatable could be a better solution.

When setting the ARM9 system control register, use the computed
cpuctrlmask value (not 0xffffffff) so that the clocking-mode bits are
not reset to FastBus mode (which isn't very fast).

* Store more information about various chip revisions,
* Implement ioctls to help the X driver detect device presence and geometry.

Introduce the INDY_R4600_CACHE config option, which more accurately describes
the code enabled by this option.
This renders #ifdef IPxx completely obsolete, thus we theoretically can unify
the GENERIC files if a workable load address relocation scheme can be found.

Addresses PR#24007 by Jaromir Dolecek <jdolecek@netbsd> and makes sh3
kernels work again after his elimination of the reaper. Tested on hpcsh.
Just before removing the vector page mapping, switch to the kernel
pmap's L1/vector page mapping so as not to pull the rug out from
under ourselves.
To prevent the stale L1/vector page mapping from being restored by
cpu_switch, replace the relevant fields of the dying process' pcb
with those of lwp0's pcb.
mace devices to their own mace/ directory. Alter conf/files.sgimips to
reflect this change in a sane manner (i.e., pull in dev/files.dev and
mace/files.mace when appropriate).
At the same time, allow crime_intr_establish() to fall through to
mace_intr_establish(). mace devices now call cpu_intr_establish().
While here, do some cosmetic changes:
* sort PCMCIA network interfaces section.
* ksyms is not a wscons related pseudo device, so move it to misc.
* line up scif at shb line, and move related options to be after it.
* move all device-specific bitbanging to the device drivers in question --
i.e., the ip32 init code doesn't access the CRIME registers directly but
instead trusts the CRIME driver to DTRT. machdep.c is cleaner thereby.
* introduce int.c, which handles the interrupt-controller goo formerly
in ip2x.c.
* unify the CPU interrupt handler, with CRIME, INT2, and the various timer
handlers hooked in via pointers in the platform struct.
* eliminate ip2x.c and ip32.c. After the interrupt handler cleanup, the
actual platform-dependent code was so minimal (rev identification, mask level
initialization) that it made sense to move it into machdep.c
* "#ifdef DEBUG printf("foo"); #endif" becomes aprint_debug.
Tested on my ip22 and ip32. Discussed with pooka@, rafal@.
Remove the vestigal sysbeep device and replace it with the same kind of
mechanism that pckbd(4) uses to find the bell, which is just as ugly, but
more standard. Adapt beep(4) to the new world (though I'm not sure it
deserves to live).

Fixes PR sparc64/20675.
Many thanks to Paul Kranenburg for hints on a similar problem he fixed
for the sparc port.
- delete ktrsyscall32()
- add a check #ifdef _LP64 to do the conversion if P_32 is set to the
standard ktrsyscall()
- add a couple of similar _LP64/P_32 checks to the systrace code.
this should get systrace working for 32 bit apps as well as complete
ktrace support for "trace_enter/trace_exit" using platforms such as amd64.
XXX: systrace isn't supported on sparc64 currently... (it doesn't use
trace_enter/trace_exit, or have it's own calls to systrace_xxx()...)
files for machines I know to have genuine PCI slots. As sent to tech-kern
for feedback in December 2003. Based on feedback, opencrypto is commented
out in the macppc GENERIC (due to absense of GENERIC_SOFTINT support),
