Fix some typos in comments.

Clear out the vestigial support for the Simtec Hydra board. Now that we're
getting support for proper SMP ARMs, keeping non-functional support for
a seriously crippled not-really-SMP system is likely to cause more problems
than it's worth, even if it was fun for a while.

branches: 1.28.10; 1.28.18;
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.

Remove arm support for IPKDB.

It hasn't worked since arm was broken out from arm32 in Jan 2001, and
no-one has noticed or cared to fix it.

branches: 1.26.28; 1.26.32; 1.26.34; 1.26.40; 1.26.48;
Finally remove the old, pre-wscons, acorn32 console code. This dated back
to RiscBSD and had been lurking in dark corners scaring people (mostly me)
for far too long. It will be missed, but not much, and I hope we can clear
up any fallout before 5.0.

While I'm in the area, also remove rpckbd(4), since pckbd(4) has
been supported on acorn32 for ages.

branches: 1.25.4; 1.25.8;
merge ktrace-lwp.

branches: 1.24.4;
rside is really a wdc. So make it a wdc.
XXX rside should be renamed to wdc_rsbus

branches: 1.23.8; 1.23.10;
Add support for iomdkbc, pckbd, and pms. Don't enable pckbd in any default
config because the X server shipped with 1.6 didn't support it, and it seems
rude to break people's X servers when they upgrade their kernels.

Add support for using ppbus(4) on acorn32. Only tested to the extent that it
attaches correctly.

cleanup old lpt(4) attachment, and glue ppbus in so that they can coexist:
* lpt device is defined in MI place (dev/ppbus/files.ppbus), dev/ic/lpt.c
is included there too; dev/ic/lpt.c is not included if ppbus is
configured or if there is alternative platform lpt (like for pc532)
* g/c MD lpt definitions and custom puc/upc attachments,
glue moved to conf/files and dev/pci/files.pci respectively; remove
device lpt definition from dev/isa/files.isa
* add ppbus parport attribute, atppc device attachments, adjust plip and lpt
glue

Add conf framework support for riscstation. Add a rsbus as this allows
acccesses with addresses shifted by the amount specified in the cookie.

Also make the inclusion of the wscons file the resposibility of whoever
includes files.iomd. (found while attempting to checking riscstation
support into evbarm)

Following Matt Thomas's request, rename ata attribute to ata_hl, and
wdc_base to ata. We can now have
atabus* at ata?
in kernel config files.

Add atabus

branches: 1.17.8;
Remove footbridge and isadma glue -- these no longer seem to be necessary.

Second phase of Hydra attachment: All CPUs are now set up sufficiently that
they can call printf(), which they do before halting.

Beginnings of support for the Simtec Hydra multiprocessor board.
So far, the Hydra is detected and initialised, and each slave CPU is
spun up briefly to check that it works.

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.

Kill options XSERVER: nothing referred to it anyway.

Pull out config(8) input for arch/arm/iomd code into files.iomd, since that's
clearly where it belongs. Normalise the whitespace in the moved text.

audio -> audiobus rename.

Complete renaming of opms to opms (was partly named pms, externally and
internally). Move arm/iomd/pms* to arm/iomd/opms*. Mechanical change,
tested by cross-compiling a kernel from i386.

Approved by christos.

XXX: What are arm/arm32/conf.c and arm/include/conf.h good for?

Jason claims that nothing tests for RISCPC any more. Make it so.

The COMPAT_OLD_BOOTLOADER flag can go now since BtRiscBSD is no longer
suported due to ELF transition.

branches: 1.7.2;
Use the MI DP83905 support for media selection on those cards that use it.

if_ne_pbus needs the "mx98905" attribute.

- 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

Move the interrupt-related file declarations into port-specific
config descriptions so that each port choose whether or not to
use it.

The ARM, Ltd. floating point emulator has moved to arch/arm.

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\""

Initial commit of the splitting off of arch/acorn32 from arch/arm32.

The IOMD/VIDC combination is now moved to arch/arm/iomd together. These
files still need a lot of cleaning up :( .... esp. the RC7500 support that
is still dormant in it; this needs either to be removed or split out for
RC7500's ``VIDC'' video/audio variant.

Apart from the RC7500 support wich is still in arch/arm32 the
iomd,vidc,riscpc and podulebus subdirectories of arch/arm32 can be removed.

This split still uses some small parts of arch/arm32 .... those are the MI
parts that haven't been moved yet.

RiscPC/A7000 have been tested and confirmed to build as should NC.
