The device tree is a data structure for describing hardware. Rather than hard coding every detail of a device into an operating system, many aspect of the hardware can be described in a data structure that is passed to the operating system at boot time.
For your convenience – all device tree files (dtb) for our designs are included in the SD Card boot partition. Sometimes it's desired to change certain device tree properties permanently.
For example a custom board has a different reference clock.
This specifies any shell prompt running on the target
