[PATCH] powerpc: Split out PCI address cache to its own file

Browse Source 
25-pci-address-cache.patch

The core EEH file is rather large. This patch splits out a self-contained
chunk of it into its own file.  This is the chunk that performes the
caching and lookup of pci devices based on the i/o addresses of thier
resoures.  This code is almos architecture-independent and could be
used by any system that wanted to find a pci device based only on
the i/o address used by the device.
