[PATCH] ppc32: Support for 82xx PQII on-chip PCI bridge

Browse Source 
This patch adds on-chip PCI bridge support for the PQ2 family.  The
incomplete existent code is updated with interrupt handling stuff and
board-specific bits for 8272ADS and PQ2FADS; the related files were renamed
(from m8260_pci to m82xx_pci) to be of more generic fashion.  This is
tested with 8266ADS and 8272ADS, should work on PQ2FADS as well.
