From 2ad7ce334819f2f2d1e8bd06b160126b41591d07 Mon Sep 17 00:00:00 2001 From: Brad Bishop Date: Sun, 9 Jul 2017 23:41:49 -0400 Subject: mapper: Generate an environment file Mapper will soon consume four command line arguments that limit the scope of watched path and interface namespaces. Add tooling to generate this environment file based on a new bitbake variables. Add xyz-openbmc_project and org-openbmc by default in the Phosphor layer and other layers can add additional namespaces as needed.
