From 7372ca68227930d03cffa548310524cad5b96733 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Fri, 2 Feb 2007 12:44:22 +0100 Subject: [PATCH] [PATCH] Correctly display PCI arbiter en-/disabled on some 4xx boards Previously the strapping DCR/SDR was read to determine if the internal PCI arbiter is enabled or not. This strapping bit can be overridden, so now the current status is read from the correct DCR/SDR register.
