Here are the notes from yesterday’s meeting. Props to Daniel Thompson for taking notes!
Note: I didn’t capture the full list of attendees. If you were there, but aren’t in the list then let me know so I can add you to the official list. Eventually I’ll post these notes on a wiki for the project.
12 April 2018 Attendees - Grant Likely (Arm) - Ryan Harken (Linaro) - Ruchika Gupta (NXP) - Tom Rini (Konsulko) - Peter Robinson (Red Hat) - Alex Graf (SUSE) - Daniel Thompson (Linaro) - Ben Eckermann (Incomplete list; Did not get full list of dial ins)
Agenda: - Status and action item updates - Other business
Notes: Status - No progress on legal issues to get things shared for outside contributions - No progress on converting EBBR to sphinx document
Devicetree - Committee meeting will shrink scope to cover governanceissues (process, release process, etc). - Will be starting a regular technical sync up call soon
AOB - EBBR and different architectures - Alexander Graf has started talking among u-boot team about extending linuxefi support more widely - Udit K: What to do about architectures that are not yet in UEFI? # Grant: Not really in scope for EBBR, they should work with UEFI forum - Grant: EBBR should be opt in (i.e. architecture representatives join us) rather then encompassing “everything” - Udit K: What about big endian? - Grant: Not UEFI… it merely looks like it. - Tom: EBBR references other specifications, needs other specifications to take big endian before we move on it - Udit K: How to handle devicetree updates? - Grant: DT owned by platform is important, not discussed how to update it - Grant: Should we create a DT specific section in EBBR? - Udit K: Ideally, yes. We understand devicetree is owned by the platform but we have had better results using the devicetree in the kernel - Peter: UEFI capsules? - Alexander: Could use overlays to cope with difference between kernels - Alexander: We cannot assume DTs will always be backwards compatible - Grant: Historically have worked to ensure new kernels work with old devicetrees but not old kernels with new DTs - Need to make sure firmware can always be recovered to a ‘safe’ state, and that DT updates don’t require reflashing the entire firmware.
Action: form sub team to draft DT update requirements.
When can others contribute? - Expect to get things tidied up this week but the mailing list is open please discuss things here!

Thanks, Michal
