I want to implement a Callback Function (04E08H- System BIOS INT 15H) for the AMD Video vBIOS (ATOM BIOS Extension Functions) to support LVDS TFT Displays with AMD G-Series processors (Persimmon mainboard). What is the best way to do this in SeaBIOS?
Take a look at src/vgahooks.c. You'll want to extend that for your board.
I need some parameter like UMA base and size from Coreboot. How can I transfer this information from Coreboot to SeaBIOS?
As ruik mentions - coreboot is itself getting the info from somewhere (eg, the hardware) - if it's not too hard to have seabios pull the info directly that would be ideal.
