v1.28.0

This is a major Erlang, Buildroot, Linux and Raspberry Pi display and camera
update. Please read below and expect to spend some time on the update.

Please see the nerves_system_br v1.28.0 release notes
for upgrade instructions if you've forked this system.

• Changes

  • Elixir 1.17 and Erlang/OTP 27 support
  • Switch from the Raspberry Pi's deprecated MMAL media support to DRM and
    libcamera. This is a big change if you use the display or camera that has
    been a long time coming. Please plan some time to make the upgrade.
  • Upgrade from Linux 6.1 to Linux 6.6
  • Reduce copy/pasted definitions in the fwup.conf by extracting them to
    fwup_include/fwup-common.conf. (No functional changes)

• Fixes

  • The serial numbers returned by Nerves.Runtime.serial_number/0 now contain
    the whole serial number. If you forked this system, check the
    boardid.config and erlinit.config for the changes and to keep the
    hostname the same.
