* Completely rewrite the alpha busspace to hide the implementation from
the drivers.
* Remove legacy inx/outx support from chipset and replace with macros
which call busspace.
* Rework pci config accesses to route through the pcib device instead of
calling a MD function directly.

With these changes it is possible to cleanly support machines which have
more than one independantly numbered PCI busses. As a bonus, the new
busspace implementation should be measurably faster than the old one.

- Properly keep track of I/O port resources.
- Use bus_space_read/write() to access the ports.

Use config's conditional compilation rather than using #ifdefs that make
modular compilation harder. I'm doing this because people seem to like
cut/pasting examples of bad practices in existing code.

Add the new keyboard driver and video card driver. They will be

Use the same method for detecting actual presence of AT-style keyboard
controller as we use in boot blocks (querying status register until
bit 1 goes off). If that doesn't happed during reasonable period assume
that the hardware doesn't have AT-style keyboard controller. This makes
FreeBSD working almost OOB on MacBook Pro (still there are issues with
putting second CPU core on-line, but since installation CD comes with
UP kernel with this change one should be able to install FreeBSD without
playing tricks with hints). Other legacy-free hardware (e.g. IBM NetVista
S40) should benefit from this as well, but since I don't have any I can't
verify.

It should make no difference on the ordinary i386 hardware (since in
that case that hardware already would be having an issues with A20
routines in boot blocks). I don't know much about AT-style keyboard
controller on other platforms (and don't have dedicated access to one),
therefore, the code is restricted to i386 for now. I suspect that amd64
may need this as well, but I would rather leave this decision to someone
who knows better about the platform(s) in question.

I have tested this change on as many "ordinary i386 boxes" as I can get
my hands on, and it doesn't create any false negatives on hardware with
AT-style keyboard present.

- Hook up the new locations of the atkbdc(4), atkbd(4) and psm(4) source
files after they were repo-copied to sys/dev/atkbdc. The sources of
atkbdc(4) and its children were moved to the new location in preparation
for adding an EBus front-end to atkbdc(4) for use on sparc64; i.e. in
order to not further scatter them over the whole tree which would have
been the result of adding atkbdc_ebus.c in e.g. sys/sparc64/ebus. Another
reason for the repo-copies was that some of the sources were misfiled,
e.g. sys/isa/atkbd_isa.c wasn't ISA-specific at all but for hanging
atkbd(4) off of atkbdc(4) and was renamed to atkbd_atkbdc.c accordingly.
Most of sys/isa/psm.c, i.e. expect for its PSMC PNP part, also isn't
ISA-specific.
- Separate the parts of atkbdc_isa.c which aren't actually ISA-specific
but are shareable between different atkbdc(4) bus front-ends into
atkbdc_subr.c (repo-copied from atkbdc_isa.c). While here use
bus_generic_rl_alloc_resource() and bus_generic_rl_release_resource()
respectively in atkbdc_isa.c instead of rolling own versions.
- Add sparc64 MD bits to atkbdc(4) and atkbd(4) and an EBus front-end for
atkbdc(4). PS/2 controllers and input devices are used on a couple of
Sun OEM boards and occur on either the EBus or the ISA bus. Depending on
the board it's either the only on-board mean to connect a keyboard and
mouse or an alternative to either RS232 or USB devices.
- Wrap the PSMC PNP part of psm.c in #ifdef DEV_ISA so it can be compiled
without isa(4) (e.g. for EBus-only machines). This ISA-specific part
isn't separated into its own source file, yet, as it requires more work
than was feasible for 6.0 in order to do it in a clean way. Actually
philip@ is working on a rewrite of psm(4) so a more comprehensive
clean-up and separation of hardware dependent and independent parts is
expected to happen after 6.0.

This command causes problems with some non-compliant hardware, resulting

are affected by this problem.

Due to popularity of those models this patch is good MFC5.4 candidate.
