All three pull requests were discussed and approved, one "as is" and the two remaining ones with changes to be done.
Some brainstorming followed on the upcoming Linaro Connect EBBR "birds of a feather" session.

Pull request #138: Require FF-A compatibility with v1.2
- Will Abdelatif update U-Boot FF-A to v1.2? No memory sharing, hardcoded regions.
- Etienne: URL link is wrong. Remove chapter? Refer to FFA_VERSION chapter instead.
- -> approved (with link fix + chapter change)
Pull request #139: Recommend GOP
- Heinrich: how about very small LCDs?
- Leave recommended -> remove warning.
- Turn around: if graphics with text, then GOP?
- Remove the future requirement warning.
- Mention EFI_EDID_OVERRIDE_PROTOCOL, too.
- -> approved (with warning removed and added non-required protocol).
Pull request #140: PSCI and SMCCC min versions requirements warning
- -> approved
