[SRU] Add CM5 Lite to flash-kernel database

[Dave Jones]

[ Impact ]

flash-kernel unable to complete successfully on the CM5 Lite (also implying kernel upgrades will fail).

[ Test Plan ]

For each affected $series:

* Flash $series to SD card and move card to CM5 Lite
* Boot image on CM5 Lite
* sudo flash-kernel
* Note "Unsupported platform error"
* sudo apt install -t $series-proposed flash-kernel
* sudo flash-kernel
* flash-kernel complete successfully

To guard against regression, re-test on other supported platforms

[ Where problems could occur ]

Only the database db/all.db is changed. Test plan includes test of operation on other supported platforms to guard against regression, and checks before and after states to ensure issue is present and actually fixed.

[ Original Description ]

As reported in comment 9 of LP: #2086774 we need other matches for the CM5 Lite in the flash-kernel database. Will update for SRU template shortly. Add entry for the Raspberry Pi CM5 to the flash-kernel devices database, specifically:

Machine: Raspberry Pi Compute Module 5 Lite Rev 1.0
Machine: Raspberry Pi Compute Module 5 Lite Rev *
Kernel-Flavors: raspi raspi-realtime
Method: pi
DTB-Id: bcm2712-rpi-cm5l-cm5io.dtb
U-Boot-Script-Name: bootscr.rpi
Required-Packages: u-boot-tools

This bug was fixed in the package flash-kernel - 3.109ubuntu1

---------------
flash-kernel (3.109ubuntu1) questing; urgency=medium

  * Merge with Debian unstable (LP: #2109835). Remaining changes:
    - Add support for Raspberry Pi 2, 3, 3+, CM3, CM3+, and 4 using a
      unified bootscript (replaces upstream's entries)
      + Update pi bootscript to support all flash-kernel vars, including
        calculated devtype and partition for future USB boot support
      + Add entry for Raspberry Pi 3A+
      + Add entry for Raspberry Pi CM4
      + Add entry for Raspberry Pi 400
      + Import UC20 updates to the rpi bootscript from the snappy-dev/image
        PPA
    - Add Kernel-Flavors check to Raspberry Pi entries
      + Support "raspi" kernel flavor
    - use umount -l in the cleanup function, else we fail while finishing up
      with the script
    - add a diversion for update-initramfs to live-installers
      post-base-installer.d to avoid update-initramfs runs before flash-kernel
      is configured
    - add a check for the diverted update-initramfs to flash-kernel-installer,
      so it gets reverted before we try to call update-initramfs
    - make post-base-installer.d/01flash-kernel-diversion actually an
      executable shell script
    - make sure that /dev is bind mounted in /target when running
      update-initramfs from flash-kernel-installer, else we do not find the
      boot media (this is only a workaround, actual fixing of the netinst
      environment is needed to fix this properly)
    - drop the "|| true" from the initramfs building code, if we fail here we
      actually dont want to attempt to flash that
    - Do not run flash-kernel inside an LXC container
    - Migrate default /etc/default/flash-kernel content to new default without
      asking via debconf
    - Filter the selection of 'latest' usable kernel through the whitelist.
    - Do not fail if there are no specified Kernel-Flavors for this machine.
    - flash-kernel/functions: Stop attempting to install the latest kernel
      if we request an older version, just refuse to act without --force.
    - Look for dtbs in /lib/firmware/$kvers/device-tree/ in find_dtb_file()
    - Allow us to find DTBs in both the old flat layout and the new vendor
      subdirectory layout, so we keep backward compatibility
    - Add support for gzip-compressed kernel images
    - Fix mkimage_kernel tests
    - Add tests for android-related functions
    - Add "pi" value for the "Method" field which copies all dtbs and
      overlays to the boot partition and provides defaults for the boot
      paths of the kernel, initrd, and u-boot script.
      + This fixes upgrades to support the Pi 4 on Bionic
      + Permit initrd to be missing in flash-kernel
      + Make U-boot optional in the "pi" method. From Groovy onwards, U-Boot
        will be an option in the boot chain but not activated by default.
        For the time being, the U-Boot-Script-Name will remain in the Pi
        entries, but this commit permits it to be blank in future.
      + Copy the Pi's bootloader firmware. At present, the Pi's bootloader
        firmware is being copied to the boot partition by the pos...

Verified on plucky on CM5 lite and regular Pi 5 (to guard against regression). On CM5 lite: current release version failed as expected, proposed version succeeded. Both versions worked on Pi 5.

[Dave Jones (waveform)]

Verified on oracular on CM5 lite and regular Pi 5. Same story as plucky.

[Dave Jones (waveform)]

Thanks to @davidcunningham for the verification attempt on noble. You're correct that currently this can't work on noble as it's not going to boot without that dtb. However, I'm going to mark that release verification done because, while it's not *sufficient* to support CM5 lite, it is *part* of a pre-requisite to support the CM5 lite on noble (we also need to add that dtb to the linux-raspi package).

After manually copying the missing dtbs (bcm2712-rpi-cm5l-*.dtb) to the boot partition (and kernel firmware path) of the noble image, verification proceeded as on oracular / plucky: current released version of flash-kernel fails as expected ("unsupported platform"), while proposed version completes successfully (both release and proposed also tested on Pi 5 to guard against regressions).
