Hello,
No, afaik the VGA rom is only needed for native gfx init on (some) devices with embedded graphics but not for add-on pci(e) cards.
Ok.
It seems like you are not using SeaBIOS. Normally, Seabios initializes PCI devices. Are you sure you are using the same coreboot configuration that worked fine for your GTX660 with this ATI card or did you rebuild/reflash coreboot inbetween?
It is the same rom I was using with the GTX660. No changes. Seabios was starting fine, menu quickly appeared after coreboot init was done.
I don't have enough knowledge to interpret cbmem output but I was wondering if something was wrong before Seabios payload execution ? Is the Ati card detected ? Only Aspeed VGA controller seems to be recognized.
Also, what is meaning of this :
"link_width=2, lane_mask=ffPcieLinkTraining port=c:lc current state=2030506" ?

Thank you,
