Subject: [PATCH] powerpc: convert to generic pci_*_flags
Date: Fri,  8 Jul 2011 21:21:24 -0500
From: Rob Herring <robherring2@gmail.com>
To: linuxppc-dev@lists.infradead.org
CC: Rob Herring <rob.herring@calxeda.com>,	Benjamin Herrenschmidt

monstr@monstr.eu, linuxram@us.ibm.com

From: Rob Herring <rob.herring@calxeda.com>

This converts powerpc to use generic pci_set/add/has_flags functions from
asm-generic/pci-bridge.h.

Compiled on 86xx and G5.

This is part of a ARM PCI clean-up which moves the microblaze pci flags
functions to asm-generic/pci-bridge.h.
