Some notes: - This currently needs a special modified HostBoot - It's missing the "ibm,thread-groups" property to inform Linux about big cores - We need to look at HMI issues, as in some cases TFAC errors get only sent to one half but both half need to rendez-vous, so we need to "trigger" an error in the other half as well. The above aren't blockers, it should be possible to merge this first.
