From 47df8f03f4cae5cec1f42856916a3dd0d0460dc1 Mon Sep 17 00:00:00 2001 From: York Sun Date: Mon, 10 Jan 2011 12:02:57 +0000 Subject: mpc8xxx: Enable ECC on/off control in hwconfig Add fsl_ddr:ecc=on in hwconfig. If ECC is enabled in board configuration file, ECC can be turned on/off by this switch. If this switch is omitted, it is ON by default. Updated hwconfig calls to use local buffer.
