From 89b78095681fd3dfd359082ba62d80551a114ab0 Mon Sep 17 00:00:00 2001 From: York Sun Date: Mon, 8 Oct 2012 07:44:27 +0000 Subject: powerpc/mpc8xxx: Add auto select bank interleaving mode Based on populated DIMMs, automatically select from cs0_cs1_cs2_cs3 or cs0_cs1 interleaving, or non-interleaving if not available. Fix the message of interleaving disabled if controller interleaving is enabled but DIMMs don't support it.
