Bug Description
[ Impact ]
This version includes support for the Pi 400 (which was unavailable at Focal's release), and for pattern matching against the machine's model in the dtb (e.g. "Raspberry Pi *"). This is necessary for flash-kernel to operate successfully on Pi models booted with out of date firmware (e.g. older boot firmware marks the Pi 400 as "Raspberry Pi ? Rev 1.0"). Hence, back-porting this version to Focal is a pre-requisite for Pi 400 support.
[ Test Case ]
* Flash Ubuntu 20.04 image to an SD card
* Boot SD card on an older Pi model (e.g. 3B) and run apt update && apt upgrade (this is required as the focal release firmware cannot boot on the 400)
* Reboot SD card on the Pi 400
* Attempt flash-kernel; note failure with "unsupported platform"
* Enable proposed; upgrade flash-kernel to proposed version
* flash-kernel should run successfully during upgrade (regardless of whether /proc/device-
[ Regression Potential ]
Minimal; the diff from 3.100 (groovy current) to 3.103 (sid) is minimal (board additions to the database and some new translations), whilst the ubuntu changes we're SRUing are already present in groovy and have been working happily there since release.
The diff from 3.98 (focal current) to 3.100 (groovy current) appears more substantial but is largely benign. Specifically, a lot of definitions in db/all.db are shuffled around as 3.100 imposed an alphabetical ordering on the file. Furthermore, two machine definitions are dropped (Linksys NSLU2 and Thecus N2100) along with their corresponding sub-architectures (ixp4xx and iop32x respectively). However, these machines have never been supported in Ubuntu (each require an unsupported kernel flavour which only exists in Debian).
