Hello
I will move all rockchip kconfig in the rockchip directory like I did for Allwinner, this will fix this.

You are using kcapi-rng but the driver do not support RNG yet. (and probably never if I continue to fail having good results with it).
So it is normal values does not change.
Thanks for your test
