graphic card support
Hi
I'm planning to use a graphic card on my U-Boot, I have 2 different PCI graphic card I can use:
ATI 3D RAGE II, Cirrus Logic 5464 and invidia RIVA TNT2.
I was wondering what should I do in order to use the PCI graphic card by the U-Boot.
Should I add only few defined to my config file and the video card will be PNP as in the network cards??
Do I need to support any special init code for the video card? or Does the U-Boot has it??
( Which platform is a good reference for using graphic card as a frame buffer/video??)
Regards

To me this looks as if it was THREE different types, not 2 ???

Add a driver for the card?

This would be really nice, but life is not that easy.

For example those using a graphics card? For example:
-> grep -l CONFIG_VIDEO_SMI_LYNXEM include/configs/* include/configs/BAB7xx.h include/configs/ELPPC.h include/configs/PPChameleonEVB.h
