14 This option adds a device-tree directory under /proc which contains
15 an image of the device tree that the kernel copies from Open
16 Firmware or other boot firmware. If unsure, say Y here.

21 This option builds in test cases for the device tree infrastructure
22 that are executed one at boot time, and the results dumped to the
23 console.
