help
The GRUB2 payload reads its runtime configuration file from etc/grub.cfg
stored in the CBFS on the flash ROM chip. Without that, it’ll just drop
into a rescue shell.
This configuration may need to be coreboot specific.
Select this option, if you want to include the GRUB2 runtime
configuration file into CBFS as `etc/grub.cfg` automatically.
You will be able to specify the path of the configuration file later.
Without this option you would need to add this file manually with
build/cbfstool build/coreboot.rom add -f grub.cfg -n etc/grub.cfg -t raw
