From 797dff97a6baa3a0a391cb7326c458807051adc9 Mon Sep 17 00:00:00 2001 From: Winston Hudson Date: Mon, 17 Nov 2014 10:17:35 -0700 Subject: MLK-9769-19 Add ARC4-ECB support for CAAM in i.MX6 family Adds ARC4-ECB Mode support to the CAAM crypto accelerator core in the i.MX6 family of SoC devices. Note that CAAM also goes by sec-4.0 or sec-5.0 in other product families (such as QorIQ). Thus the property names are often tied to the sec-4.0+ nomenclature.
