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.

Still hardcoded for Tyan S1846.
This slightly increases performance, but it's still pretty horrible.
Some RAM settings are causing a dramatically slow system (confirmed
by comparing memtest performance results of the proprietary BIOS
and our code). Haven't found the problem, yet.

As per JEDEC, we should wait 200us until voltages and clocks are stable.
Then apply NOPs for 200 clock cycles (for simplicity we use 200us here).
All other delays are so low that we get away with just waiting 1us.

- Only check the RAM from 0 - 640 KB and 768 KB - 1 MB now. That's
available on all boards, regardless of what DIMMs you use.
Tested on the Tyan S1846, works fine.
- Properly set the PAM registers to allow the region from 768 KB - 1 MB
to be used as normal RAM (required for the above).
- Document all of this properly. Add/improve other documentation, too.
- Simplify and document code in northbridge.c.
- Cosmetics and coding style.

This does _not_ fully work, yet. You will _not_ be able to boot any
payload with this code, yet.
Add missing license headers.
Base the northbridge.c file on the Intel 855PM version, that comes
closer to what we want.
The raminit.c file is written from scratch and hardcodes several
values for now. This needs to be fixed later by reading the
correct values via SPD.

This adds support the start of support for an Asus p2b

Bitworks IMS board. Reads from the SMbus don't work.
Moving dump_spd_registers() into its own private copy

included in src/sdram to only do one memory controller.
