[Severity: Low] Were vdev1vring0 and vdev1vring1 intentionally left behind? The patch removes vdev0vring0, vdev0vring1, vdevbuffer, and rsc_table, stating these remoteproc regions will be added via overlay. Leaving vdev1vring0 and vdev1vring1 behind unnecessarily reserves 64KB of physical memory that Linux cannot use.
