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).
