From b0b867462c569e7accd6f78c942cbab028116ecf Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 29 Oct 2009 15:04:35 +0100 Subject: ppc4xx: Consolidate 4xx PCIe board specific configuration This patch consolidates the PPC4xx board specific PCIe configuration code. This way the duplicated code is removed. Boards can implement a special, non standard behaviour (e.g. number of PCIe slots, etc) by overriding the weak default functions.
