Notes

PRs

#55: Prefer to handle via DT spec if possible. Similar wording proposed for DT spec (and quick side-by-side during meeting looks OK).

Issues

#47: How much, if any, of secure platform requirements to we want in scope for EBBR? Can always split out at a later stage.

#56 & #57: Reminders after mailing list discussion. Still waiting for patches...

#58: Storage location of device trees. Still expect firmware to provide a default DTB. However perhaps standardizing a tools to help navigate unstable DTs (e.g. when distro wants to provide updated DTs whether they can merge). "Prefered design is not to have unstable DT evolution". Custom EFI boot service to provide fixups (would allow grub to fetch a DT from root/bootfs and apply firmware knowledge)? No consensus at this stage!

Changes to DT spec

0.4 DT spec is brewing, will include text from pr #55 above.

Next release

Time based releases? Feature driven releases?

RISC-V PRs should provoke a release a sensible time after merging.
