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