VGA rom can not be loaded by SEABIOS

[Wang, Qingpei]

Hi,

With the latest version of seabios, the vgarom can not be loaded
correctly. I find that in the code seabios/src/optionrom.c vga_setup

Can to load the vga rom from cbfs.

The detail log is attached.

Hi,
I had a similar problem some time ago. I mistakenly set
CONFIG_OPTIONROMS_DEPLOYED 1 and it should be 0.

Did you enable CONFIG_COREBOOT_FLASH in SeaBIOS' src/config.h file?
Be sure to follow the steps at:

hi Kevin,
   I have already found the problem.  Coreboot now use cbfs to organize the
option rom. The vga.rom may be renamed like pci1002,731F.rom. But in
seabios/optionrom.c it just check the filename with prefix "vgaroms/" which
can not load the vgarom.
  maybe coreboot should organzie the vga rom in a different way which can
let seabios detect.

SeaBIOS will load roms of the form "pciVVVV,DDDD.rom".  I don't see
any messages from SeaBIOS about checking CBFS though, which makes me
wonder if CONFIG_COREBOOT_FLASH is set.

Can you also post the output of "cbfstool print".
