0b0771d180 Attached patch fixes at least one issue ;) During the PCI BAR sizing must be the
D1F0 bridge without activated I/O and MEM resources, otherwise it will hang
 whole PCI bus.

 U-boot is also disabling the IO/MEM decode when sizing the BARs, dont know why
 does we not.

 Second small change just changes a bit which controls the PSTATECTL logic.

 Third change deals with the integrated VGA, which needs to be enabled early,
 so the VGA_EN is set along the bridges, and PCI K8 resource maps are set
 correctly. Finally the CPU accessible framebuffer is now disabled as it is not
 needed.

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.

c221349746 Following patch will setup KT890 HT automatically. It will find the
max width of the link and also it will take the frequency of K8 HT
already done coreboot (and checks if t can run on it).

dd52e17448 Following patch fixes the retrain/reset sequence which caused problem with some
nVidia cards. The enable link should be enough, retrain is done there.

Tested on my system.

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

70ab323ae6 Various cosmetic fixes and improvements (trivial).
- Use 'static' where appropriate.
 - Use 'const' where appropriate.
 - Indentation fixes.
 - Add comment wrt init code which is only valid for VT8237R.

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.

f1cf1f7c3a Ever wondered where those "setting incorrect section attributes for
rodata.pci_driver" warnings are coming from? We were packing those
structures into a read-only segment, but forgot to mark them const.

Despite its size, this is a fairly trivial patch created by a simple
search/replace
