armv8 SHA-256 using ARMv8 Crypto Extensions
This patch adds support for the SHA-256 Secure Hash Algorithm for CPUs
that have support for the SHA-256 part of the ARM v8 Crypto Extensions.
It greatly improves sha-256 based operations, about 17x faster on iMX8M
evk board. ~12ms vs ~208ms for a 20MiB kernel sha-256 verification.
asm implementation is a simplified version of the Linux version (from
Ard Biesheuvel).
