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.
fwts exists as a snap package that can be run from the operating system. I had not problem with running it on ARM64 systems. Cf. https://snapcraft.io/fwts.
Do you relate to to the live image that gave you problems?
