[U-Boot-Users] graphic card support

[Ronen Shitrit]

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.

Yes.

No.

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
