	  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
	  Documentation/dev-tools/kunit/.

	  If in doubt, say "N".
