They are built automatically using the main `make` command. To build the device tree binaries (.dtb) from the device tree sources (.dts) separately, we can build all of them at once using:

```bash

$ make generate # optionally override BUILDROOT

$ make devicetrees # optionally override BUILDROOT

The .dts files will end up in the `<BUILDROOT>/output/images` folder of your chosen buildroot directory.
