Title:
Update firmware for hwe/oem kernel migrations
Status in linux-firmware package in Ubuntu:

Status in linux-firmware source package in Focal:
Fix Committed
Status in linux-firmware source package in Jammy:

Status in linux-firmware source package in Lunar:

Bug description:
[SRU Justification]
[Impact]
When migrating to a new hwe kernel or introduced a oem kernel of a
newer version, the firmware blobs might not match the expectation of
the new kernel. For example, a hwe-5.15 on Focal may include new
drivers that relies on firmware blobs that are only available in Jammy.
[Fix]
A previously obsoleted (and removed in Kinetic and Lunar) script
`list-lts-update-files` is used to enumerate firmware blobs to be
backported. It's retored and revised with additional support to
pick the right blobs especially in regard to ath and iwlwifi drivers.
On Focal, the commits in need are enumerated by:

Commit 05b5dc001 and 36f2ea9f7 include updates to other existing files,
so they are dropped from this SRU. An additional commit that modifies
only WHENCE, commit 0b558e8a7, found when resolving conflicts, were also
added.
On Jammy,

xargs git log --graph --oneline jammy..kinetic --

Commit 4ffcf980a involves rename existing files in WHENCE, so ignored.
While Jammy has 3 additional oem kernels, they were also tested:
$ debian/scripts/list-lts-update-files jammy kinetic \
../oem-5.17/debian.oem/abi/fwinfo | \
xargs git log --graph --oneline jammy..kinetic --
(no new commits)
$ debian/scripts/list-lts-update-files jammy lunar \
../oem-6.0/debian.oem/abi/fwinfo | \
xargs git log --graph --oneline jammy..lunar --
* 06dbfbc74 iwlwifi: add new FWs from core69-81 release
$ debian/scripts/list-lts-update-files jammy lunar \
../oem-6.1/debian.oem/abi/fwinfo | \
xargs git log --graph --oneline jammy..lunar --
* 51fff4e69 i915: Add versionless HuC files for current platforms
On Lunar, while it's not an LTS series and there will not be any hwe/oem
kernel backported, the only change proposed is the script itself.
[Test Case]
To ensure no exiting bits being overwritten, the changes are reviewed
manually.
[Where problems could occur]
These firmware blobs are only referenced in the new hwe/oem kernels, and
shall not have side effect. On Focal and Jammy, while we have rolled out
oem and hwe kernels a long time ago, these changes will enable the
corresponding hardware that were meant to be enabled along with the
oem/hwe kernel migration at the time.
[Other Info]
While there is no hwe/oem kernel planned for Kinetic, and unlike the
devel series Lunar, adding this script to it is quite meaningless, so
it's not nominated for fix here.
