Hi,

On my custom board based on 405EXr /dev/random produces no output
at all, and /dev/urandom is not random enough for our purposes. 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.

Felix.
