bool "Device Tree and Open Firmware support"
help
This option enables the device tree infrastructure.
It is automatically selected by platforms that need it or can
be enabled manually for unittests, overlays or
compile-coverage.

depends on OF_IRQ
select OF_EARLY_FLATTREE

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.
config OF_ALL_DTBS
bool "Build all Device Tree Blobs"
depends on COMPILE_TEST
select DTC
help
This option builds all possible Device Tree Blobs (DTBs) for the
current architecture.
If unsure, say N here, but this option is safe to enable.

# need it.

bool "Support for dynamic device trees" if OF_UNITTEST
help
On some platforms, the device tree can be manipulated at runtime.
While this option is selected automatically on such platforms, you
can enable it manually to improve device tree unit test coverage.

Overlays are a method to dynamically modify part of the kernel's
device tree with dynamically loaded data.
While this option is selected automatically when needed, you can
enable it manually to improve device tree unit test coverage.
