This feels weird: OpenSSL provides an optimized software implementation of various cryptographic transforms. It doesn't depend on any particular hardware per se. The reason it supports only a subset of the platforms supported by FreeBSD is that the implementations are CPU-specific, and each one requires work to port to ossl. In other words, this isn't a hardware offload driver such as qat or safexcel, so the traditional hardware section of the driver manual doesn't make as much sense.

It would be somewhat useful to list the CPU features required for ossl to be usable on each of these platforms, like the aesni and armv8crypto pages do. What do you plan to do for those pages? I can help draft some corresponding text for ossl.

Those pages need hardware sections, because this year I was cleaning out lines from the original hardware notes in the 90s. The only way the hardware notes is maintainable is if everything is pulled in automatically. I don't really understand this stuff, so if you would help that would be amazing.
