Title:
  Warn upgraders of Pi 4 EEPROM requirements

Status in flash-kernel package in Ubuntu:
  Invalid
Status in ubuntu-release-upgrader package in Ubuntu:
  Fix Released

Bug description:
  Users on the Pi 4 upgrading to questing (and the forthcoming resolute)
  should be warned if their boot EEPROM version is earlier than
  2022-11-25, as earlier EEPROMs cannot deal with the newer boot layout.

  This test is only necessary on the Pi 4; earlier models do not have a
  boot EEPROM, and the Pi 5's boot EEPROM was recent enough at release.
  A reasonable test would probably be to check for the 2711 CPU in
  /proc/cpuinfo, the presence of the rpi-eeprom-update script (which is
  seeded and should always be available on a Raspberry Pi install), and
  the bootloader timestamp extracted from the runtime device-tree.

  In the event the boot EEPROM is too old, u-r-u should simply abort the
  upgrade, and inform the user why. It must *not* attempt to force the
  EEPROM update itself.
