aeb6c9870f sb/via/k8t890: add vga textmode code for k8m890 chrome igp.
Add initialisation for the VIA Chrome 9 IGP on the k8m890 through native code
and through the general vga infrastructure i committed a month or two ago.
Add videoram_size option for k8m890 and the Asus M2V-MX SE.

Now the Asus M2V-MX SE will magically come up with a working standard VGA
80x25 textmode.

Many thanks to the people who worked hard on the Asus M2V-MX SE, and all
of its components; this vga bringup was a breeze thanks to your hard work
for this excellently supported board. And separate thanks to Rudolf Marek
for spurring me on and for providing a register dump.

316e07fb04 Following patch adds K8M890 support. It initializes the AGP and graphics UMA.
The V-link setup and HT bridge is redone, because VT8237A has it in another
device. So far following combination of chipsets should now work:

K8T890CE + VT8237R
K8M890(CE) + VT8237R

VIA PC1 brige moved to NB code (vt8237r_bridge.c -> k8t890_bridge.c) and
notes about K8M890 support were added.

7e61e45402 Please bear with me - another rename checkin. This qualifies as trivial, no
code is changed.

a6ddf253ad Fine-tune the V-link bus between K8T890 and VT8237R and set
it to 8X transfer rate (up to 1066 MB/s) similar code placed here would be
needed for VT8237A/S etc. Using VIA recommended values despite they are for
K8T890CF, this is K8T890CE (still dont know what is exactly different).

This patch enables the parity error reporting on V-Link, so it enables NMI
generation for the SERR# errors. The NMI may not be generated, maybe port
61h needs some tuning too.
