NAK. RNG is needed to seed standard distros.
You have this backwards, setting WITH_SOFTWARE_PRNG=y forces the SW RNG, disabling the HW RNG. Without this line the HW RNG is the default.
That is not the rationale with which the series was posted. I would prefer we use HW RNG by default. but as I understand there are a bunch of f/w bugs preventing us from doing so. if they are resolved, then the commit message argument should be that the bugs are fixed, so we can easily use then with f/w version x.y.z onwards.
