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.
