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.

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
	  module will be called amd-rng.

	  If unsure, say Y.

config HW_RANDOM_GEODE
	tristate "AMD Geode HW Random Number Generator support"
	depends on HW_RANDOM && X86_32 && PCI
	default HW_RANDOM
	---help---
	  This driver provides kernel-side support for the Random Number
	  Generator hardware found on the AMD Geode LX.

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

	  If unsure, say Y.

config HW_RANDOM_N2RNG
	tristate "Niagara2 Random Number Generator support"
	depends on HW_RANDOM && SPARC64

	---help---
	  This driver provides kernel-side support for the Random Number
	  Generator hardware found on Niagara2 cpus.

	  To compile this driver as a module, choose M here: the
	  module will be called n2-rng.

	  If unsure, say Y.

config HW_RANDOM_VIA
	tristate "VIA HW Random Number Generator support"
	depends on HW_RANDOM && X86_32
	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.

config HW_RANDOM_IXP4XX
	tristate "Intel IXP4xx NPU HW Random Number Generator support"
	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.
