Split early startup code out of locore.S into locore0.S. Adjust link
run so that this locore0.o is always at the start of the executable.
But randomize the link order of all other .o files in the kernel, so
that their exec/rodata/data/bss segments land all over the place.

The bootstrap code will need smashing because it is mapped by BLTB,
but this is a bit involved so not done yet.

As a result, the internal layout of every newly build bsd kernel is
different from past kernels. Internal relative offsets are not known
to an outside attacker. The only known offsets are in the startup code
(which will be gone when it is smashed).

Ramdisk kernels cannot be compiled like this, because they are gzip'd.
When the internal pointer references change, the compression dictionary
bloats and results in poorer compression.

move mem.c to hppa directory like every other arch.
(probably landed in dev because it has support for this viper thing,
but i like consistency for the /dev/null parts.)

Remove all audio format conversion code from the kernel (btw holding

bluetooth support doesn't work and isn't going anywhere. the current

remove iop(4) driver. it is entirely unmaintained and supports something
which basically doesn't exist at all.
reminded about it by brad

Work-in-progress driver for the HP ``Audio1'' device found on the HP 9000/425e
(hp300) and the HP9000/705 and 9000/710 (hppa). 8-bit mono, 8KHz, no surprise
since it is based upon a digital phone chip.
Tested on 425e only so far, and playback only; configured in, but disabled,
on hppa kernels until there are positive test reports (I am not sure the
interrupt assignment on hppa is correct).
And now people no longer can joke about audio on hp300.

Implement pckbc_xt_translation() in gsckbc. Thus, we can attach pckbd instead of
gsckbd; the former will cause a proper translation page to be selected by
the keyboard.

Because of this, we no longer depend on the page the keyboard is left in
by the PDC (page 2 for all machines but the PrecisionBook, which is in
page 3), and there is no longer any need to use separate keyboard maps.

Enable hme(4). Reported to work by Stian Sletner.

Add gecko(4), a driver for the GeckoBOA BC GSC+ port.

neccessary -> necessary; from Pierre Riteau

crank maxusers on some architectures

libkern, begone. Move to a new mechanism where config(8)'s "file"
directive can select between MI and MD versions of these files. At
the same time, adjust the boot programs to pick exactly what they need,
instead of the 7 or 8 mechanisms previously used.

There will be some fallout from this, but testing it all by myself is a
ridiculously slow process; it will be finished in-tree.

Various developers were very nice and avoided making fun of me when I
was gibbering in the corner..

Define a new attribute, pckbcslot, which pckbc and gsckbc provide, and to
which pckbd and pms attach. This makes it simpler to add new controllers
pckbd/pms can attach to.

Add missing bits for siop@gsc.

Add support for Zalon NCR 53C720 FW SCSI.

lcd(4); a driver for the front panel LCD display found on the four-digit

Delay switching to the real serial console until we attach the serial device.

some comments on the pci bridges and dino is at phantomas not mainbus

Put a pckbc-like "slot" locator for gsckbc children. Even if this has no
sense inthe gsckbc world, the code currently requires this for proper
attachment. Oops.

Add hil devices, and enable wsdisplay at sti and wskbd at gsc and hil.

More leftovers from when we thought we could attach a pckbc to gsc

Enter gsckbc, a driver for the ps/2-like input device ports found on many
hppa machines, and gsckbd, a driver for the ps/2-like keyboard.

Both are derived from pckbc and pckbd, but the differences in port wiring and
keyboard behaviour prevented the creation of a thin pckbc wrapper.

Currently, only us and uk keyboard layouts are provided.

The adventurous person can enable gsckb[cd], wsdisplay at sti and wskbd,
but this will only work correctly on machines featuring a modern-prom sti
graphics device, and a ps/2 keyboard port.

better osiop at gsc attachment and kill dead siop from files.hppa

Merry Christmas Mickey!

First cut at osiop driver (LSI Logic/Symbios/NCR 53C710). For hppa
only at the moment.

Functional for the most part, but there are known problems:

1) SCSI_CHECK/REQUEST_SENSE not handled at all - simply returns a
zero'ed scsi_sense_data buffer. As a result all osiop sc_link's are
created with the ADEV_NODOORLOCK quirk to suppress PREVENT_ALLOW
commands from being issued (and failing) during probe.

2) Sync negotiation (wide is not supported on this chip) needs to be
validated due to some ominous comments in the source about being valid
only for the 33Mhz Zeus board.

3) Probe message needs fixing/completion to issue useful info. See 2).

4) Timeout/hangs occur under heavy load, e.g. make builds.

From NetBSD.

newer machines use phantom bus to attach lasi and other bus adapters.

change the device scanning technique to both include a full device path
in the attach_args and do proper shifting in the pdc_scanbus() and
add a device for the newer machines as well as use a newer device
