Enable radeondrm(4) on loongson to get accelerated graphics
with the RS780E chipset.

OK kettenis@, jsg@

Add a PCI attach hook mechanism for htb(4), similar to the one
in bonito(4). Use the hook for setting up the PIC.

Discussed with miod@ long ago

Add SMP config and IPI control logic for Loongson 3A.

Extend struct platform with MP control functions, and add bootstrap code
for secondary CPUs.

Discussed with miod@

Determine the available CPUs.

Move the definition of REGVAL into a common header to make it usable
outside bonito(4).

ok miod@

Update the loongson codebase to recognize the so-called `EFI-like' interface
supposedly provided by newer PMON firmware (on Loongson 2Gq and Loongson 3A
systems).

Remove dependency from wscons_machdep upon bonito. Instead of hardcoding bonito
as the northbridge, have the per-platform early setup code register functions

Remove dependency from wscons_machdep upon bonito. Instead of hardcoding bonito
as the northbridge, have the per-platform early setup code register functions
providing access to the PCI configuration space, for the wscons code to walk the
PCI space in search of a graphics board.

No functional change yet.

Huge work-in-progress commit to support Loongson 2E-based evaluation boards
with a VIA 686 southbridge.

Features:
- 686 setup code (no thanks to PMON for not initializing the beast).
- work in progress ISA interrupt handling code.
- support for vga(4) compatible devices as console, in PC-compatible text mode.
- move legacy (ISA) support code out of bonito(4) to make things clearer.
- support more than 256MB on 2E-based systems.

Tested on a generic 2E-based evaluation board by someone who wishes to remain
anonymous; you know who you are, thank you very much for testing.

Allow for two more per-platform function pointers, one for extra setup work

Add reset and powerdown code to the fuloong 2f platform; this also fixes
reset on yeeloong.

Blind support for the EMTEC Gdium Liberty netbook. Per-platform configuration
is moved to specific files, and a pointer to the key configuration structure
is now kept in struct sys_config.
bonito(4) interrupt handling is split, to allow PCI+Legacy interrupt systems
(Lemote Yeelong) and PCI-only Legacy-free systems (Gdium) to coexist
peacefully.

Define struct cpu_hwinfo, to hold hardware specific information about each
processor (instead of sys_config.cpu[]), and pass it in the attach_args
when attaching cpu devices.

This allows per-cpu information to be gathered late in the bootstrap process,
and not be limited by an arbitrary MAX_CPUS limit; this will suit IP27 and
IP35 systems better.

While there, use this information to make sure delay() uses the speed
information from the cpu it is invoked on.

By popular demand and peer pressure, check-in work in progress work to support
the Yeelong Lemote mips-based netbook. Kernel bits only for now, needs
polishing; most of this work done during h2k9 last month, although the
porting effort started earlier this year.
