From e738c5f15562635c02a03365cb62cad35051babe Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 18 Oct 2018 13:57:22 +0000 Subject: [PATCH] powerpc/8xx: Add DT node for using the SEC engine of the MPC885 The MPC885 has SEC engine version 1.2 with the following details: - Number of Crypto channels: 1 - Exec Units: DEU, MDEU and AESU - Available descriptors: 00010, 00100, 00110, 01000, 11000, 11010 It is also supposed to have descriptor 00000, but it doesn't work properly so we keep it out for the moment.
