Suggestions on how to deal with noble and oracular/devel welcome as we
don't yet have Tegra images for these series!

Title:
  Seeds and metapackages for Tegra

Bug description:
  Hi,

  Canonical maintains a set of kernels and images for NVIDIA Tegra Orin
  based systems for Ubuntu 22.04/jammy in collaboration with NVIDIA,
  with intentions to also support 24.04 and probably other series in the
  future.

  The image definition for Tegra images is fairly simple:
  https://git.launchpad.net/ubuntu-images/tree/ubuntu-server-tegra-igx.yaml?h=jammy
  but has to manually pull a number of packages such as:
  - nvidia-tegra-defaults (currently just ships a GRUB config to expand the console= parameters to include the specific Tegra serial console)
  - grub + shim as to have a path to update these boot artifacts on installed systems

  Contrast this to RPi images which just refer to seeds
  https://git.launchpad.net/ubuntu-images/tree/ubuntu-server-pi-arm64.yaml
  this is because there are RPi specific seeds pulling in the bootloader – flash-kernel  (ubuntu-seeds/platform/raspi-common) – and raspi specific packages – rpi-eeprom (same seed)

  Similary, the Tegra images don't currently include a WiFi stack, but
  just like RPi, they should as the Tegra system-on-modules come with a
  WiFi chip that we want to enable out of the box in Ubuntu. Here again,
  this is achieved in Raspberry Pi images by listing wpasupplicant in
  the raspi-common seed used in both desktop and server images.

  Hence, I think we need to add tegra seeds similar to the raspi ones,
  and similar metapackages. In the future, probably the bootloader bits
  should be selected through some more scalable mechanism somewhere
  between ubuntu-image and seeds. Wireless support should perhaps be in
  some kind of Ubuntu for IoT seed or similar, as to not clutter server,
  but share a common definition of how we expect to deliver WiFi in RPi
  like embedded systems.

  We also want to have Tegra seeds to have a mean to pull packages into
  main, such as nvidia-tegra-defaults.

  Best,
