-Subject: [PATCH] scripts: Makefile: Enable creation of _symbols_ DT node for
- overlays
-
-DT compiler supports -@ flag which indicates that _symbols_ node should be
-automatically created during compilation.  This node is required for
-using DT overlays.  The generated DTB is backward compatible, the _symbols_
-node can be safely ignored if overlays are not used.
