Hi Naman,
Presently, arm64 isn’t a supported architecture for coreboot in emulation, mainly due to the fact that the port we have runs in 32-bit for bootblock and romstage stages. I would work to re-structure this and get these stages running in 64-bit.
Just wanted to make sure you know that we were also planning to rework the whole bootblock and romstage mess on ARM64 in the near future for a Chromium project. When you get to that part in your project please let me know what you're planning to do so we can avoid doing the same thing twice and stepping on each other's toes.
(Also, not sure if you know this already but we did use to have an emulation/foundation-armv8 port already that I think even somewhat booted as some point. It just fell into disrepair with latter changes but it might still be a useful starting point.)
