# Hardware Random Number Generator (RNG) configuration
#

config HW_RANDOM
	tristate "Hardware Random Number Generator Core support"
	default m
	---help---
	  Hardware Random Number Generator Core infrastructure.

	  To compile this driver as a module, choose M here: the
	  module will be called rng-core.  This provides a device
	  that's usually called /dev/hw_random, and which exposes one
	  of possibly several hardware random number generators.

	  These hardware random number generators do not feed directly
	  into the kernel's random number generator.  That is usually
	  handled by the "rngd" daemon.  Documentation/hw_random.txt
	  has more information.

	  If unsure, say Y.

config HW_RANDOM_TIMERIOMEM
	tristate "Timer IOMEM HW Random Number Generator support"
	depends on HW_RANDOM && HAS_IOMEM
	---help---
	  This driver provides kernel-side support for a generic Random
	  Number Generator used by reading a 'dumb' iomem address that
	  is to be read no faster than, for example, once a second;
	  the default FPGA bitstream on the TS-7800 has such functionality.

	  To compile this driver as a module, choose M here: the
	  module will be called timeriomem-rng.

	  If unsure, say Y.

	default HW_RANDOM
	---help---
	  This driver provides kernel-side support for the Random Number
	  Generator hardware found on Intel i8xx-based motherboards.

	  To compile this driver as a module, choose M here: the
	  module will be called intel-rng.

	  If unsure, say Y.

config HW_RANDOM_AMD
	tristate "AMD HW Random Number Generator support"
	depends on HW_RANDOM && X86 && PCI
	default HW_RANDOM
	---help---
	  This driver provides kernel-side support for the Random Number
	  Generator hardware found on AMD 76x-based motherboards.

	  To compile this driver as a module, choose M here: the

	default HW_RANDOM
	---help---
	  This driver provides kernel-side support for the Random
	  Number Generator hardware found on the Intel IXP4xx NPU.

	  To compile this driver as a module, choose M here: the
