be enabled manually for unittests, overlays or
compile-coverage.

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.
This option should only be enabled for a development kernel. The tests
will taint the kernel with TAINT_TEST. The tests will cause ERROR and
WARNING messages to print on the console. The tests will cause stack
traces to print on the console. It is possible that the tests will
leave the devicetree in a corrupted state.
The unittest output will be verbose. Copy the output to a file
via capturing the console output or via the dmesg command. Process
this file with scripts/dtc/of_unittest_expect to reduce the
verbosity, test whether expected output is present, and to
summarize the results.
If unsure, say N here. This option is not safe to enable.
