From cc8e839abc80887ae832767b5930d40edd6d7eb7 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Fri, 28 Mar 2008 14:09:04 +0100 Subject: ppc4xx: Canyonlands: Print SATA/PCIe configuration and board revision Canyonlands (460EX) shares the first PCIe interface with the SoC SATA interface. This usage can be configured with the jumper J6. This patch displays the current configuration upon bootup and changes the PCIe init loop, to only initialize the availabel PCIe slots.
