feature: Possibilty for a Coreboot payload mode like GRUB2?

[EliasTheGrandMasterOfMistakes]

Coreboot provides a libpayload for payloads providing boot systems.

have a future plan for coreboot support?

[mintsuki]

I am aware of coreboot and libpayload, but I am not sure what tangible benefit this would bring compared to the effort of implementation. That said if someone did it themselves I wouldn't be against merging it, depending on the quality of the code.
