[PATCH 0/6] x86: efi: Add a 64-bit coreboot payload

[Simon Glass]

This series creates a new 64-bit 'coreboot64' build which can be launched
from coreboot. It uses SPL to effect the jump to 64-bit mode.

This was done in an attempt to get the Ubuntu FirmwareTestSuite[1]
working. Unfortunately the latest version shows a splash screen and hangs,
perhaps due to some missing EFI support.
