Title:
  Support for Ubuntu Core tegra-igx images in jammy

Status in livecd-rootfs package in Ubuntu:
  Fix Released
Status in livecd-rootfs source package in Jammy:
  Fix Released

Bug description:
  This bug is to track changes needed to be able to build jammy Ubuntu
  Core images for arm64+tegra-igx to support hardware based on NVIDIA
  Tegra SoCs. NB some initial support had already been backported; see
  LP #2015644.

  [ Impact ]

   * This allows building missing image flavors for the NVIDIA Tegra families of hardware, notably Ubuntu Core images for the tegra-igx subarch.
   * This should also allow building of classic ISO installer images for tegra-igx, albeit that's a lesser priority.

  
  [ Test Plan ]

   * Changes to livecd-rootfs were tested locally and can be tested from the -proposed package by building a Core image for tegra-igx as follows:
  sudo apt install livecd-rootfs
  mkdir build
  cd build

  rm -rf auto local config
  rm -f livecd.*.model-assertion
  mkdir -p auto
  for s in config build clean; do ln -s /usr/share/livecd-rootfs/live-build/auto/$s auto/; done
  lb clean --purge
  export PROJECT=ubuntu-core ARCH=arm64 SUBARCH=tegra-igx SUITE=jammy IMAGEFORMAT=ubuntu-image CHANNEL=edge
  lb config
  sudo -E lb build

  
  [ Where problems could occur ]

   * Changes are relatively light, but in the case of a regression for
  instance due to broken logic, this could break existing image builds,
  in which case an older livecd-rootfs could be reuploaded.

  
  [ Other Info ]

   * These images are still being developed and its possible further
  changes are needed as we iterate through the maturity of the image.
