Is there a git supermodule (i.e. a git repository containing a .gitmodules files and managed using the git submodule keyword) for l4t available on https://nv-tegra.nvidia.com ? And if not,
could one be made available ? I surmise that is already used internally at nvidia. That would be
easier than source_sync.sh to track the changes in the names and number of subrepositories in the development of l4t.
