** Description changed:
+ [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
+ * sudo add-apt-repository ppa:waveform/firmware
+ * 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.
