menuconfig ENTROPY_NRF5_RNG
	bool "nRF5 RNG driver"
	# FIXME: nRF5 RNG driver can't co-exist with Bluetooth's HAL

	help
	  This option enables the RNG peripheral, which is a random number
	  generator, based on internal thermal noise, that provides a
	  random 8-bit value to the host when read.

config ENTROPY_NRF5_BIAS_CORRECTION
	bool "Enable bias correction (uniform distribution)"
	depends on ENTROPY_NRF5_RNG
	help
	  This option enables the RNG bias correction, which guarantees a
	  uniform distribution of 0 and 1. When this option is enabled, the time
	  to generate a byte cannot be guaranteed.
