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.
