That certainly sounds reasonable, but I think better Orjan chime

So I've heard; I haven't tested it myself.

I'm listed under "Authorized Committers" as
CRIS                    Hans-Peter Nilsson
(I just fixed the email address address).

Apparently someone pruned me from the target-maintainer section,
but that's fine.  I guess we can and should find someone to put
there; I'll look into it.
