From 43cbce69d48d052574d71f50724be546d90a46a4 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 13 Oct 2008 10:45:14 +0200 Subject: ppc4xx: Correctly setup ranges property in ebc node Previously only the NOR flash mapping was written into the ranges property of the ebc node. This patch now writes all enabled chip select areas into the ranges property.
