Bug Description

[Impact]

Future Pi Zero 2 boards will have a slightly different wifi chip on board which requires a variant of the current firmware. This is being added to the rename of linux-firmware-raspi2 (to linux-firmware-raspi) for jammy, but requires adding to the existing linux-firmware-raspi2 package for focal and impish, otherwise users on newer variants of the Pi Zero 2 will find themselves without any wifi connectivity (or, in fact, any connectivity given there is no ethernet on these boards).

[Test Plan]

Boards with the new wifi chip are not yet available, so the following test plan is the best we can do:

* Flash a fresh SD card with the appropriate server image
* Boot the card on the Pi under test with *no* ethernet attached (if the board supports it)
* Edit /etc/netplan/50-cloud-init.yaml to include an appropriate wifi configuration for your local AP
* sudo netplan apply
* ip addr # verify wlan0 is up and has a valid address
* Enable -proposed and update
* sudo apt install linux-firmware-raspi2
* sudo reboot
* ip addr # verify wlan0 is up and has a valid address

This should be performed on all supported boards with wifi (3B, 3A+, 3B+, 4B, 400) on both supported architectures (armhf, and arm64).

[Regression Potential]

As we're updating the wifi firmware, the obvious possible regression is failure of the wifi interface (hence the testing of all supported boards in the plan).

[Original Description]

In the upstream wifi firmware package (version 1:20210315-3+rpt3 of the firmware-nonfree package), the following is noted in the changelog: "Future Zero 2 W boards will have an alternative version of 43436 that should have different firmware, named brcmfmac43436s-sdio". We need to incorporate these blobs to support future variants of this board.

The updated firmware is now in jammy-proposed under the renamed linux-firmware-raspi package. SRUs will for impish and focal will be under the original linux-firmware-raspi2 name.

Hello Dave, or anyone else affected,

Accepted linux-firmware-raspi2 into impish-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/linux-firmware-raspi2/6-0ubuntu0~21.10.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-impish to verification-done-impish. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-impish. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

Hey Dave! Can we get some more verification information + verification on impish as well?

Tested on focal with Pi 3, Pi 4, and Pi Zero 2 -- boot still working happily (pending gadget changes for the Zero 2), along with wifi. Currently testing impish...

Likewise for impish, all booting and wifi working correctly, verification done.
