Move the TI Keystone hardware random number generator into the
same menu as all of the other hardware random number generators.
This makes the driver config be listed in the correct place in
the kconfig tools.

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.
