Plus, I'd point out that _no one_ is talking about boot protocols. Not outside linaro at any rate. Which means that they're doing effective closed-door discussion.
I'm not sure whether by "outside linaro" you mean "outside some kind of top secret Linaro meetings". I went to an open meeting of Linaro developers touching on exactly these kind of topics, and everything was public and there was substantial interest.
For the record, this Linaro topic and the progress done is documented here: https://blueprints.launchpad.net/linaro/+spec/linaro-kernel-o-bootarchitectu...
Nothing (yet) in there that would highly passionate you Russell I'm afraid. This is probably why you didn't hear of it before. But the discussion and the mailing list is public and open to anyone interested.
I'm not a Linaro developer; but I have CC'd their boot-architecture list which AIUI is where some of the Linaro folks were thinking of discussing boot protocols.
Just to be clear: I don't have a particular axe to grind, except that I would like there to be some kind of defined and reasonably stable interface, and that obviously we (Xen.org) need that interface to support access to Hyp mode (which is something that Linux needs too if we are to have a properly supported KVM on ARM).
Are linux-arm-kernel@infradead and boot-architecture@linaro the right places to try to have this conversation ?
Absolutely.
