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