And I can start GRUB2 menu just issuing in UEFI shell (in /boot/efi/EFI/fedora) grubx64.efi!

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.

Re: [coreboot] Coreboot with an UEFI payload to boot (Clover) an Thinkpad X230 Hackintosh

So I’ve tried Coreboot/TianoCore (on chip) + Grub2(EFI)/Ubuntu (on disk), and it did’t worked. I have a black screen with a blinking cursor (top left screen). I’ve tried with Clover/macOS instead of Ubuntu, same result. In the mean time, I’ve tried the stock UEFI Bios (on chip) + Grub2(EFI)/Ubuntu (on 1st disk, 1st to boot) + Clover(EFI)/macOS (on 2nd disk), well, Grub(EFI) can boot Clover (which boot macOS). So I’ve tried to build a Grub2 EFI as payload for Coreboot, but without success. When building Grub2, there is the "—with-plaform=" option, and it’s either —with-plaform=coreboot or —with-plaform=efi. It doesn’t seem to be possible to select both. And of course Grub2 build —with-plaform=coreboot cannot boot Clover (nor macOS). So for now, I’m stuck.. Maybe I’ll try Coreboot/Seabios/Duet(Tianocore) So with Coreboot/Seabios/Duet, I’ve got this screen https://www.dropbox.com/s/82kaan9osz2znoo/duet-screenshot.jpg?dl=0 for half a second, then reboot, repeatedly.

Thank you very much. This is 100% duable: Coreboot + payload Tiano Core (flash), which will boot GRUB 2.0 from drive, then show GRUB 2.0 boot menu with original MacOS (if you can overwrite Clover with GRUB 2.0, not affecting MacOS). I'll give you here the hint: you should see, using stock UEFI BIOS, /boot/efi directory, which is FAT32 formatted (if you can enter BIOS UEFI shell), where you can see either Clover executable (cloverx64.efi or similar name), either grubx64.efi, if you correctly have overwritten Clover with GRUB 2.0. If you do not have ability to enter UEFI shell on stock UEFI BIOS, you can, using original MacOS probably see /boot. and find there efi/ directory, And inspect it yourself (maybe you can from MacOS overwrite Clover with GRUB 2.0, and do inspection at the spot). As the addendum, you should take your Ubuntu HDD/SSD, installed with SeaBIOS as payload, then using Coreboot + payload Tiano Core in flash, reinstall from scratch Ubuntu (making it UEFI compatible). In such a case, your SINGLE Coreboot + Tiano Core flash FW will satisfy all your needs, since you will use x230 with various UEFI compatible OSes.
