From f0be44f4fb1faee42635ca5ea06dc9c3e820a35d Mon Sep 17 00:00:00 2001 From: David McCullough Date: Fri, 7 Sep 2012 04:17:02 +0800 Subject: arm/crypto: Add optimized AES and SHA1 routines Add assembler versions of AES and SHA1 for ARM platforms. This has provided up to a 50% improvement in IPsec/TCP throughout for tunnels using AES128/SHA1.
