Subject: [PATCH 0/6] Description for PCI patches using platform driver

This series of patches are to unify pci initialization code and add PM

support

quoted

for all 85xx/86xx powerpc boards. But two side effects are introduced

by this

quoted

mechanism which listed below:

1. of_platform_bus_probe() will be called twice but in some cases

duplication

quoted

   warning occured. We fix this in [PATCH 5/6].

2. Edac driver failed to register pci nodes as platform devices. We fix

this

quoted

   in [PATCH 6/6].

With these patches will not the SWIOTLB will not be initialized even if
PCI/PCIe demanded?

These patches still have the swiotlb init problem if "ppc_swiotlb_enable" i=
s
only demanded by PCI/PCIe. One of the purposes of sending out these patches
is to let us start a discussion for this problem in upstream.
