20 device-tree and all the overlays to be compiled with the *-@* command line
21 switch of the device-tree compiler so that symbol information is included.
28 Building a binary device-tree overlay follows the same process as building a
29 traditional binary device-tree. For example:
85 1. Figure out where to place both the base device tree blob and the
86 overlay. Make sure you have enough space to grow the base tree without
