From fe9c4593b5469b08f9195d5ffe09783e2ea50689 Mon Sep 17 00:00:00 2001 From: Eneas U de Queiroz Date: Tue, 19 Apr 2022 12:02:09 -0300 Subject: wolfssl: enable CPU crypto instructions This enables AES & SHA CPU instructions for compatible armv8, and x86_64 architectures. Add this to the hardware acceleration choice, since they can't be enabled at the same time. The package was marked non-shared, since the arm CPUs may or may not have crypto extensions enabled based on licensing; bcm27xx does not enable them. There is no run-time detection of this for arm. NOTE: Should this be backported to a release branch, it must be done shortly before a new minor release, because the change to nonshared will remove libwolfssl from the shared packages, but the nonshared are only built in a subsequent release!
