   4 Subject: [PATCH] scripts: Makefile: Enable creation of _symbols_ DT node for
   5  overlays
   6
   7 DT compiler supports -@ flag which indicates that _symbols_ node should be
   8 automatically created during compilation.  This node is required for
   9 using DT overlays.  The generated DTB is backward compatible, the _symbols_
  10 node can be safely ignored if overlays are not used.
