Ack, we just went through this with the last update and all hit
https://github.com/openbmc/openbmc/issues/1030.  It was pretty
disruptive for all of us in the lab needing to pull the chips and
manually flash each.  This is would be fine if we can just flash the
<system>.all.tar and all works ok, but that was not what we found in
https://github.com/openbmc/openbmc/issues/1030.
