config PROC_DEVICETREE
bool "Support for device tree in /proc"
depends on PROC_FS && !SPARC
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"
depends on OF_IRQ
help
This option builds in test cases for the device tree infrastructure
that are executed once at boot time, and the results dumped to the
console.
If unsure, say N here, but this option is safe to enable.
