+ 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.
