---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.
