There is PKA/TRNG driver for sure. Let me check if it was accepted in opensource yet. Otherwise I will forward you the driver which may not be there in opensource yet.

Saving entropy pool between reboots doesn't help much. What can be done to increase the entropy of the system ? I was thinking of adding IRQF_SAMPLE_RANDOM to network driver, but since not too many drivers implement it, I don't know whether it's a good idea or not. Is there any work in progress to develop hw_random driver for 4xx TRNG ? Thanks a lot.
