Post-Merge checklist

• Checklist:
  • Install instructions
  • Notes about SUNXI_SETUP_REGULATORS and minimal supported arm-trusted-firmware version (>=2.8.14)
  • Contrib EFI support to linux-postmarketos-linux - See https://gitlab.com/postmarketOS/pmaports/-/merge_requests/4774, tldr it's using non-standard kernel that is introducing a breaking noise in the development so decided to work on linux-lts package instead
  • Contrib SPI support to linux-postmarketos-linux - Appears to be included in alpine's linux-lts
  • Fix Suspension and Hibernation - Broken due to lack of crust dependency in upstream alpine's u-boot, @mps said to be working on implementing that
  • [-] Fix Audio -- Appears to depend on userland configuration will be addresed in upcoming merge request
  • [-] INFO: PSCI: Suspend is unavailable - Expects fixes in Alpine Linux to add crust in the u-boot-sunxi package
  • [-] "GNOME only works if xfce4 is installed" - confirmed, seemingly userland issue
  • [-] The GPT Table gets corrupted upon installation due to u-boot flashing - pmbootstrap issue
