From 95bcaa39053ff518021572ca00ebf626ee8cbaf8 Mon Sep 17 00:00:00 2001 From: Shengzhou Liu Date: Fri, 13 Jul 2012 17:49:21 -0500 Subject: [PATCH] crypto: caam - add backward compatible string sec4.0 In some device trees of previous version, there were string "fsl,sec4.0". To be backward compatible with device trees, we first check "fsl,sec-v4.0", if it fails, then check for "fsl,sec4.0". Signed-off-by: Shengzhou Liu extended to include new hash and rng code, which was omitted from the previous version of this patch during a rebase of the SDK version.
