Provide a new kconfig option which can be used to disable the default seeding of the host standard library random generator by this driver. This allows some other component to do so without this component default initialization interfering. Signed-off-by: Alberto Escolar Piedras <alberto.escolar.piedras@nordicsemi.no>

This option enables the test random number generator for the
|
|
native_posix board (ARCH_POSIX). This is based on the host random() API.
|
|
Note that this entropy generator is only meant for test purposes and does
|
|
not generate real entropy.
|
|
It actually generates always the same sequence of random numbers if
|
|
initialized with the same seed.

Apply a seed by default, even if the user does not request it through the command line.
|
|
Disabling this feature allows some other component to seed the host standard library random
|
|
generator without this component's default initialization interfering.
