Bug Description
Impact
======
The current stable release (bionic) does not support booting on the Raspberry Pi 4. Several packages need back-porting from devel to support this, along with a new kernel.
Bionic back-port branch:
Focal branch:
Builds of packages for both releases available from the following PPA (along with all packages required for testing the bionic back-port):
https:/
Test Case
=========
* Attempt to boot the latest bionic image (18.04.3) on a pi4; note failure
* Move the SD card to a pi3 and boot successfully
* Ensure all packages are up to date (apt update/upgrade)
* sudo add-apt-repository ppa:waveform/pi4
* sudo apt upgrade
* sudo reboot
* Ensure boot proceeds successfully on the pi3
* Verify facilities (USB peripherals, USB mass storage, wifi, bluetooth, audio, etc.) work
* sudo apt install linux-image-
* sudo reboot
* Ensure boot proceeds successfully on the pi3
* Verify facilities (USB peripherals, USB mass storage, wifi, bluetooth, audio, etc.) work
* Move the SD card back to the pi4
* Ensure boot proceeds successfully on the pi4
* Verify facilities (USB peripherals, USB mass storage, wifi, bluetooth, audio, etc.) work
* Repeat for both archs (armhf and arm64)
Regression Potential
=======
Plenty; pi4 support on bionic requires back-ports of flash-kernel, u-boot, linux-firmware-

Looks fine, I have sponsored this for eoan. This doesn't explicitly require an FFe because it's basically a bugfix for the new pi4 support that we already had an FFe for.
