In configurations with CONFIG_KUNIT=m, builting the unit test
into the kernel causes a link failure:
arm-linux-gnueabi-ld: drivers/gpu/drm/vc4/tests/vc4_mock.o: in function `__build_mock':
vc4_mock.c:(.text+0x6e): undefined reference to `kunit_do_failed_assertion'
arm-linux-gnueabi-ld: vc4_mock.c:(.text+0x9c): undefined reference to `kunit_do_failed_assertion'
arm-linux-gnueabi-ld: vc4_mock.c:(.text+0x100): undefined reference to `kunit_ptr_not_err_assert_format'
...
Allow this to be a loadable module as well to have Kconfig
sort out the dependencies correctly.

Choose this option if you have a system that has a Broadcom

VC4 GPU, such as the Raspberry Pi or other BCM2708/BCM2835.

|
This driver requires that "avoid_warnings=2" be present in
|
|
the config.txt for the firmware, to keep it from smashing
|
|
our display setup.

This builds unit tests for the VC4 DRM/KMS driver. This option is
|
|
not useful for distributions or general kernels, but only for kernel

|
developers working on the VC4 driver.

For more information on KUnit and unit tests in general,

please refer to the KUnit documentation in

If in doubt, say "N".
