This is useful since it allows U-Boot to configure itself according to what it finds there. If you have a number of similar boards with different peripherals, you can describe the features of each board in the device tree file, and have a single generic source base. Put your device tree file in board//dts/_.dts. It will be picked up and built into the image. To do ===== - Provide a way for U-Boot to find a device tree somewhere in memory on startup, similar to how the environment works.
