config HW_RANDOM
tristate "Hardware Random Number Generator Core support"

---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

config UML_RANDOM
depends on UML
tristate "Hardware random number generator"
help
This option enables UML's "hardware" random number generator. It
attaches itself to the host's /dev/random, supplying as much entropy
as the host has, rather than the small amount the UML gets from its
own drivers. It registers itself as a standard hardware random number
generator, major 10, minor 183, and the canonical device name is
/dev/hwrng.
The way to make use of this is to install the rng-tools package
(check your distro, or download from
http://sourceforge.net/projects/gkernel/). rngd periodically reads
/dev/hwrng and injects the entropy into /dev/random.
config HW_RANDOM_PSERIES
