Sorry, a typo. I meant the 4.9 release :) 4.10 release is an open
question. This should be in production quality by 4.9-rc4/5 in order
to make that happen.

The good timeline for topic branch would be end of Oct before LPC so
that I could carry a setup involving Minnowboard and a discrete TPM
module and demo this. I already have a topic branch called 'tabrm'
in place for the same conference.
