From 1095493a5d4c16f481a783f6f54d83ad0e07dfa0 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 12 Nov 2009 12:00:49 +0100 Subject: ppc4xx: Consolidate pci_target_init() function This patch removes the duplicted implementations of the pci_target_init() function by introducing a weak default function for it. This weak default has a different implementation for 440EP(x)/GR(x) PPC's. It can be overridden by a board specific version (e.g. PMC440, korat).
