So is there some userspace part to go with this now?

FWIW I've not looked into it - is it just a case of someone knocking 
out some JSON from the MMU-600/700 TRMs, or is there still mroe to do? 

That should just be it.

I had the impression that *some* part of the process was stalled until 
implementations can start providing meaningful IIDRs, but I wasn't 
sure whether that was tooling or just data. I just work the low-level 
enablement angle :)

Tooling should be ok, but I would just like to see more of these JSONs 
so any tooling issues can be ironed out.

Sounds good - Jean, Leo, is that something Linaro might like to pick up 
as part of the PMCG interest, or shall I make a note on my to-do list 
for the new year?

Thanks,
Robin.

Cheers,
John
