Device Tree overays are a method used to update the Device Tree. Given a device tree that describes all the devices, let's say you add a new SPI device, you can update the device tree with a (blob) device tree overlay.

I should ask (without Googling), What is the Device Tree Overlay mechanism in RTEMS?

    What are device tree overlays?
