It prepares the introduction of device tree overlays that are not applied on device trees at compile time (dtbo files.) These device tree overlays will be used by either a bootloader or a linux userspace tool to extend the base device tree. This is used e.g. for drivers that need device tree nodes for optional non plug and play devices, like an external DSI touchscreen panel that embeds different i2c devices to control it.
