[U-Boot] [PATCH 2/3] ppc4xx: Consolidate pci_pre_init() function
Stefan Roese
sr at denx.de
Fri Nov 13 11:24:06 CET 2009
This patch removes the duplicted implementations of the pci_pre_init()
function by introducing a weak default function for it. This weak default
has a different implementation for some PPC variants. It can be
overridden by a board specific version.
