Following the work done here [1], this set provides support for the remoteproc core to release resources associated with a remote processor without having to switch it off. That way a platform driver can be removed or the application processor power cycled while the remote processor is still operating.
Modifications for this revision are detailed in the changelog of each patch but the main difference is that going from RPROC_RUNNING -> RPROC_DETACHED is no longer supported to avoid dealing tricky resource table issues. Applies cleanly on rproc-next (e8b4e9a21af7). I will rebase on 5.12-rc1 when it comes out next week.
