I'm kind of keen to get rid of these, instead maybe having something in
a well known data structure and maybe a watchdog... While useful for
seeing if *everything* has wedged, they're often enough that all the
rest of the skiboot log vanishes if you don't reboot your system as
often as firmware developers do.
