This option adds a device-tree directory under /proc which contains
|
|
an image of the device tree that the kernel copies from Open

Firmware or other boot firmware. If unsure, say Y here.

This option builds in test cases for the device tree infrastructure

that are executed one at boot time, and the results dumped to the
|
|
console.
|

If unsure, say N here, but this option is safe to enable.
