bool "Support for device tree in /proc"

help
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.
config OF_SELFTEST
bool "Device Tree Runtime self tests"
help
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.
