Public bug reported:
Impact
======
Apt upgrades performed on a Raspberry Pi 4 complain about missing
database entries during the flash-kernel trigger. An updated version of
flash-kernel with a Pi 4 entry in the database is available in the
following PPA:
https://launchpad.net/~waveform/+archive/ubuntu/ubpi4
Test Case
=========
* Boot the latest eoan daily on a pi3
* Migrate the boot config to operate on a pi4 (these steps won't be necessary
once the gadget snap is updated):
$ sudo -i
$ . /usr/share/rpi-config-migration
$ is_old_config && migrate_config
* Reboot the card on a pi4
* Run sudo /usr/sbin/flash-kernel
* Without the upgrade, it will report "Unsupported platform" with exit code 1
* Upgrade package to 3.98ubuntu4
* Re-run sudo /usr/sbin/flash-kernel
* With the upgrade, should report the usual "Using DTB: bcm2711-rpi-4-b.dtb",
etc. with exit code 0
Regression Potential
====================
None; this change only adds the Pi 4 entry to the flash-kernel db. It
doesn't alter / remove any existing entries or change any code. The
worst case scenario is that it still doesn't work on the Pi 4.
