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_INTEL
	tristate "Intel HW Random Number Generator support"
	depends on HW_RANDOM && (X86 || IA64) && PCI
	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.

	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 VIA based motherboards.

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

	  If unsure, say Y.

	depends on HW_RANDOM && ARCH_IXP4XX
	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
	  module will be called ixp4xx-rng.

	  If unsure, say Y.

config HW_RANDOM_OMAP
	tristate "OMAP Random Number Generator support"
	depends on HW_RANDOM && (ARCH_OMAP16XX || ARCH_OMAP24XX)
	default HW_RANDOM
 	---help---
 	  This driver provides kernel-side support for the Random Number
	  Generator hardware found on OMAP16xx and OMAP24xx multimedia
	  processors.

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

 	  If unsure, say Y.

config HW_RANDOM_PASEMI
	tristate "PA Semi HW Random Number Generator support"

	  Generator hardware.

	  To compile this driver as a module, choose M here: the
	  module will be called virtio-rng.  If unsure, say N.
