You're disabling the self-testing infrastructure. This is not
the same thing as the tcrypt module.

Is this for fast booting?

Cheers,

It is my intention to disable these tests since in my running them at
every boot doesn't add any value. I thought about adding a separate
Kconfig option for that, too. I want to make sure it's a sensible thing
to do.

Yes, it saves ~180 miliseconds for me at prng_mod_init(), for example.

I see. In that case please introduce a new Kconfig option for
this that defaults to testing being enabled.

Thanks!
