This is an option to be enabled by individual random driver
to signal that there is a true random driver.

help
Sets log level for random driver.
Levels are:
- 0 OFF: do not write
- 1 ERROR: only write SYS_LOG_ERR
- 2 WARNING: write SYS_LOG_WRN in addition to previous level
- 3 INFO: write SYS_LOG_INF in addition to previous levels

help
This option signifies that the kernel's random number APIs are
permitted to return values that are not truly random.
This capability is provided for testing purposes, when a truly random
number generator is not available. The non-random number generator
should not be used in a production environment.

help
This options enables number generator based on timestamp counter
of x86 boards, obtained with rdtsc instruction.

depends on TEST_RANDOM_GENERATOR && !X86_TSC_RANDOM_GENERATOR
default y
help
This options enables number generator based on system timer
clock. This number generator is not random and used for
testing only.
