From cc5d0189b9ba95260857a5018a1c2fef90008507 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Tue, 13 Dec 2005 18:01:21 +1100 Subject: [PATCH] powerpc: Remove device_node addrs/n_addr The pre-parsed addrs/n_addrs fields in struct device_node are finally gone. Remove the dodgy heuristics that did that parsing at boot and remove the fields themselves since we now have a good replacement with the new OF parsing code. This patch also fixes a bunch of drivers to use the new code instead, so that at least pmac32, pseries, iseries and g5 defconfigs build.
