Freedom metal DTS files

Hi everyone,
I’m going through freedom metal library based freedom-e-sdk document and i have came across dts files. In README file it is stated that

 * design.dts
      - The DeviceTree description of the target. This file is used to parameterize
        the Freedom Metal library to the target device. It is included as reference
        so that users of Freedom Metal are aware of what features and peripherals
        are available on the target.

Apart from being used as reference , is there any other purpose for dts file in freedom metal library?
