	  This is an option to be enabled by individual random driver
	  to signal that there is a true random driver.

	default n
	help
	  This option signifies that the kernel's random number APIs are
	  permitted to return values that are not truly random.
	  This capability is provided for testing purposes, when a truly random
	  number generator is not available. The non-random number generator
	  should not be used in a production environment.
