It is grubx64.efi, and, believe me or not, I can break/hack into my UEFI shell (which is NOT normally available to users). So I see tjhere (on UEFI shell 2.40), the SAME directories (on /boot/efi/). And I can start GRUB2 menu just issuing in UEFI shell (in /boot/efi/EFI/fedora) grubx64.efi! While doing Coreboot + Tiano Core (or UEFI) in flash & GRUB2 + Ubuntu on drive, you should check and see if you see the same as me?! At least using stock BIOS??? _______ > So I’ve tried to build a Grub2 EFI as payload for Coreboot, but without > success. Nope. You have GRUB2 on drive, already. You should build Coreboot + Tiano Core in flash (then have drive GRUB2 + Ubuntu), but here somebody from Coreboot-GOOGLE folks should give you a hand. Should work, as my best understanding is.
