  10 # NOTE: Armband patching consists of:
  11 # - clone upstream repositories to git submodules, tracking remotes;
  12 # - tag each submodule (before patching) with "${A_OPNFV_TAG}-root";
  13 # - apply Armband patches for each submodule;
  14 # - tag each submodule (after patching) with "${OPNFV_TAG}";
  15 # - stage Fuel submodule patches by copying them to Fuel f_repos/patch dir;
  16 # - pass updated repository info to Fuel@OPNFV build system
  17 #   (e.g. FUEL_PLUGIN_ODL_CHANGE="${OPNFV_TAG}") via armband-fuel-config.mk;
  18
  19 # NOTE: Long-term goals (Armband repo should merge with Fuel@OPNFV):
  20 # - all build related changes should affect Fuel@OPNFV, NOT Armband;
  21 # - Armband make/build system should only handle patching non-Fuel submodules,
  22 #   and then invoke Fuel@OPNFV's patch & build system;
  23 # - Fuel@OPNFV is made aware of an Armband type build by passing
