Various Intel 82810/82810E changes which allow onboard VGA to work.
At the same time also make the 82810 code handle 82810E.
- Set SMRAM register according to CONFIG_VIDEO_MB value:
- 512 means 512 KB
- 1 means 1 MB
- Every other value for CONFIG_VIDEO_MB (e.g. 0) disables VGA.
This is not very clean, changing CONFIG_VIDEO_MB to CONFIG_VIDEO_KB
in a future patch may be nicer.
- Set MISSC2 register bits as required per datasheet to make VGA work.
The code handles both 82810 and 82810E.
- northbridge.c: Add __pci_driver entry for the Intel 82810E.
Also:
- Rename PAM register #define to PAMR as per datasheet.
- Drop unused/commented code for now.
- Don't explicitly set GMCHCFG for now, the default works ok. We'll
have to figure out the proper/ideal settings later.
The code is based on a patch from Elia Yehuda <z4ziggy@gmail.com> but
has been modified quite a bit for correctness and minimalism.
Tested on hardware with a slightly modified MS-6178 target,
patches to enable onboard-VGA for MS-6178 will follow.
