I have a requirement to pass the state value of a GPIO (on Intel ATOM Baytrail SoC) from Coreboot to GRUB2. Based on this GPIO state, I would script the GRUB2 to configuration to select an alternative OS from the GRUB menu list. Is there a facility to pass this custom defined data from Coreboot to GRUB2?
