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.
