Subject: [RFC/PATCH 6/6] powerpc: pci32: 4xx embedded platforms want to reassign all PCI resources
Date: Wed, 05 Dec 2007 11:53:07 +1100 [thread overview]
Message-ID: <20071205005416.B362CDE1B5@ozlabs.org> (raw)
In-Reply-To: <1196815980.72143.899704305870.qpush@grosgo>
This makes 4xx embedded platforms re-assign all PCI resources as we
pretty much never care about what the various firmwares have done on
these, it's generally not compatible with the way the kernel will map
the bridges.
We still need to also enable bus renumbering on some of them, but I
will do that from a separate patch after I've fixed 4xx PCIe to handle
all bus numbers.
