Raw notes

• Pull request #142: SCMI requirements
  • Ilias: mention 1.0 everywhere necessary. Etienne agrees.
  • Referring alpha specification
  • Etienne: reference 3.2 and forget telemetry for now. 3.2 has negotiation already.
  • -> Reference 3.2
  • Issue letter probably a legacy; just remove the letter
    • Menu on Arm developer mentions only the numeric version, not the letter
      • no "alpha" even
  • Ilias -> remove F and remove alpha
  • Etienne: alpha, beta and final have the same letter?
    • Confirmed with Issue 3, version 3.2 alpha/beta/final
  • Heinrich was right, of course :)
• U-Boot AArch64 MMU permissions
  • EFI services to come
