use of ARM hwrng

[jpsollie]

(in addition to the post of porting to rk3328 below in this forum)
It is more or less up and running, now I'm trying to save as much native a53 cpu instructions as possible, using this pdf:
https://rockchip.fr/RK3328%20datasheet%20V1.2.pdf
It says, the device supports crypto extensions, and a true hardware random number generator (which I enabled inn the device tree).
How do I convince openssl to use /dev/hwrng by default instead of using /dev/urandom?
I guess it will save me some cpu cycles, but not sure how to do this[/url]
