[Bug 2067080] Re: [SRU] Please bump firmware revision to 8 from jammy

[Dave Jones]

If the bump enables the new boards to boot we will have to look at a
potential point release for focal on the Pi images.

Note to self: because this bump involves a rename of the package (from
linux-firmware-raspi2 to linux-firmware-raspi) this will also involve
adjusting the seed ... argh, which doesn't exist! The raspi seed was
added in groovy; may need to backport that as well to focal for the
purposes of rebuild. Can we even build focal images with ubuntu-image?
Need to test...

  [SRU] Please bump firmware revision to 8 from jammy

Status in linux-firmware-raspi2 source package in Bionic:

Status in linux-firmware-raspi2 source package in Focal:
  New

Bug description:
  [ Impact ]

  The rev 1.4 variant of the 3B+ requires an updated boot firmware,
  specifically one at least as recent as that in jammy-updates (version
  8). This should be back-ported to focal, and preferably bionic to
  provide support for Core 18 booting on these devices.

  [ Test Plan ]

  As a closed boot firmware this will need validation on all supported
  Pis. For bionic, this is the 2B, 3B, 3A+, and 3B+. For focal, this is
  the 2B, 3B, 3A+, 3B+, and 4B. Because the package includes wifi and
  bluetooth firmware as well as boot firmware, the following should be
  verified:

  * Ability to boot successfully
  * Ability to reboot successfully
  * Ability to shutdown successfully
  * That wifi can connect successfully on relevant models (all except the 2B)
  * That bluetooth can pair successfully on relevant models (all except the 2B)

  [ Regression Potential ]

  Fairly low; the firmware in question has been in use on all relevant
  models in jammy for quite some time, so the regression potential for
  the operation of the firmware itself is low. That said, the wifi and
  bluetooth firmware still interacts with the kernel, and bionic and
  focal have different kernel versions to jammy, hence why the operation
  of these components will still need (re-)verification.

  If issues arise they are most likely to come from the fact that linux-
  firmware-raspi2 was renamed to linux-firmware-raspi in jammy which
  affected the diversions in the package. This means the backport isn't
  *entirely* straight-forward and care must be taken to ensure that all
  relevant files end up in their correct locations with the correct
  diversions.
