At any rate, Myles, maybe you should bump the coreboot rev for s2895 in buildrom to the one you have confirmed working?
I always argued for buildrom using the latest version of Coreboot. In this case the payload (SeaBIOS) continued to evolve.
I guess there's no good way around bit rot. I'm hoping that we'll continue to improve the v2 build process enough that there will be no need for buildrom except to build payloads.
Thanks, Myles
