[coreboot] What is the way to add a VGA ROM space in target\xx\xx\Config.lb

[Bao, Zheng]

In a Config.lb like this 
(in coreboot-v2/targets/amd/serengeti_cheetah_fam10/Config.lb):

option CONFIG_USE_FAILOVER_IMAGE=0 
option CONFIG_USE_FALLBACK_IMAGE=1 
#   option CONFIG_ROM_IMAGE_SIZE=0x13800 
#   option CONFIG_ROM_IMAGE_SIZE=0x19800

option CONFIG_XIP_ROM_SIZE=0x8 
option COREBOOT_EXTRA_VERSION=$(shell cat
../../VERSION)_Fallback 
payload ../payload.elf 
end 
 
romimage failover 
option CONFIG_USE_FAILOVER_IMAGE=1 
option CONFIG_USE_FALLBACK_IMAGE=0 
option CONFIG_ROM_IMAGE_SIZE=CONFIG_FAILOVER_SIZE 
option CONFIG_XIP_ROM_SIZE=CONFIG_FAILOVER_SIZE 
option COREBOOT_EXTRA_VERSION=$(shell cat
../../VERSION)_Failover 
end 
 
#buildrom ./coreboot.rom CONFIG_ROM_SIZE normal fallback failover 
buildrom ./coreboot.rom CONFIG_ROM_SIZE fallback failover

end

We want to get a space about 50K for VGA ROM like dbm690t does. I tried
CONFIG_ROM_SIZE, CONFIG_ROM_IMAGE_SIZE, but they both don't work. What
can we do?

Hi Zheng,

Look at the example in pcengines/alix.1c:

## CONFIG_ROM_SIZE is the total number of bytes allocated for coreboot use
## (normal AND fallback images and payloads). Leave 36k for VSA.
option CONFIG_ROM_SIZE = (512 * 1024) - (36 * 1024)

So, CONFIG_ROM_SIZE is the place to do that.

Thanks,
Ward.
