Hi Krzysztof,

I tested a little bit and:
1. Seeding with some value
2. generating random,
3. kcapi_rng_destroy+kcrng_init, (I cannot do a hardware reset except
   reboot of entire system)
4. seeding with the same value as in (1) - different random numbers.

Doing a system reboot and repeating above - different random numbers
(all are different: step (2) and in (4)).

Your test case also produces different random values every time.

Then I would assume that simply adding an outer loop to your for() loop to 
inject seed larger than the minimum required seed size should be fine.

Best regards,
Krzysztof
