The only current place I could think this could be remotely possible
would be in simulator... and we should instead make the OPAL calls work
properly in the simulator for all the RTAS functionality (that we care
about).

If you mean mambo, I tested that, at least the public version, and it doesn't
provide or need RTAS.

On the other sims we ran without RTAS during the Power8 bringup, though it was
eventually used a little bit late in the cycle. In future we should be using
skiboot, or just putting logic directly into the kernel for early bringup - or
permanently :)

agreed on using skiboot. If we're going as far as booting a linux
kernel, the overhead of loading skiboot is next to nothing in
comparison. Or at least it should be.
