Upon incoming SMAF message from CPU (C3 or FID/VID change), the SB will
assert SLP# which is connected to LDTSTOP_L on K8 CPUs. Question is for how
long. Imho for 100us. Which is more than plenty (2us required) I will try
to justify this once I know what bios to set in SB.

Add missing PIRQ table to make most devices work.
Enable VGA support. Add flashrom flashing protection code.
Make CPU init actually work (result: massive speed-up).

replacing it with a minimal, but working, framework which will be expanded.
Drop a bunch of useless and duplicated files, add missing license headers.
I'm self-acking it this time, the diff is a huge unreadable mess and the old
code is broken anyway...
This code is tested to build fine, and can boot a Linux kernel up to a
login-prompt via FILO (IDE). This is verified on actual hardware.

the system boot to a command line.
This patch comments out the code to set up the vga framebuffer to allow
the system to boot, without this fix the system hangs during elfboot.
The only line that is absolutely necessary to change is the SMRAM setup,
however I've commented out all vga setup to make it very obvious to both
the kernel/payload and anyone looking at the code that vga isn't
currently working. This setup might also be better handled in
northbridge.c, if it doesn't need to be done before ram init, yet
another reason to comment it all. In the future, LinuxBIOS needs to be
told that the graphics memory area, 1mb or 512kb (at the user or
developer's option), is reserved for the onchip vga, but I'm not sure if
it's taken at the top or bottom of the memory, yet. LB may also need to
set a base address for the AGP aperture and/or be told that range is
reserved as well, whether this was originally the job of the system bios
or vga bios is still a mystery. It also corrects the number of entries
in irq_tables.c, without this fix the kernel would probably complain and
hang due to unmapped IRQs.

boot linux, but does so very slowly and fails during the boot process, probably
because of the irq tables.

minor changes, to bring them up to par. It also should remove (but might
just clean out) the irq_tables.c from both boards, because they were
just copied from Via Epia to begin with, and weren't usable. As far as I
can tell, these are the only changes needed to the targets for now,
aside from fixups to reset.c when the time comes. Both have been build
tested, but not checked on hardware since I don't have it. I have left
Uwe as the copyright holder since the only changes I've made are trivial.

and leaving enough room for a real payload (not /dev/null)
This is a wonderful example why "uses" sucks.
* add Config-abuild.lb for those boards that dont build with
the default settings and a real payload:
arima/hdama, amd/quartet, amd/serengeti_cheetah, ibm/e326
* if lzma is installed and a real payload is used, try compressing
it.
* fix a small bug in "abuild --help"
This patch is acked by me because its due to infrastructural changes only.
Flames welcome.

- New superIO winbond/w83977tf
- Add single memory controller SBbus debug routine
into a file private to the i440bx
This adds support the start of support for an Asus p2b
mainboard. Current limitations are the same as for the
Bitworks IMS board. Reads from the SMbus don't work.
Moving dump_spd_registers() into its own private copy
solves the problem of having to go hack on the version that
included in src/sdram to only do one memory controller.
