[Bug 1761483] Re: Firmware needs updating for new pi 3 B+

[Dave Jones]

** Description changed:

+ [Impact]
+ 
+  * The bionic release currently cannot boot on certain pi models (3B+, CM3+) due to outdated firmware.
+  * This is fixed in the disco and eoan releases with firmware revision 20190215, however it would be nice to enable booting on these platforms for the current LTS release.
+ 
+ [Test Case]
+ 
+  * Attempt to boot the current bionic release on a CM3+; it never gets past the rainbow screen.
+  * Flash same image onto a CM3; it boots successfully.
+  * Upgrade linux-firmware-raspi2 to the proposed revision. Reboot to ensure CM3 still boots successfully.
+  * dd image onto CM3+
+  * CM3+ should now boot successfully.
+ 
+ [Regression Potential]
+ 
+  * Minimal regression potential; I've tested the updated firmware with
+ bionic on a 3B, 3B+, CM3, and CM3+ (to ensure it fixes the issue on the
+ plus platforms, and doesn't regress on the others). All boot
+ successfully with the updated firmware.
+ 
+ [Other Info]
+ 
+  * Tested with built package (linux-firmware-raspi2 1.20190215-0ubuntu4) in https://launchpad.net/~waveform/+archive/ubuntu/pkg
+  * I can attach a debdiff if required, but I'm not sure how useful it'll be given that the important changes are simply updated binary blobs.
+  * This is not the very latest firmware available from the github.com/raspberrypi/firmware repo (the very latest includes support for the pi4), but this is intentional (issues have been discovered when testing with the very latest firmware).
+ 
+ 
+ Original description:
+ 
  A new raspberry pi (the 3 B+) was released in March 2018.  To enable
  this to boot the firmware needs updating to the latest version.
