So was thinking about this and was wondering about doing the following:

hose->cfg_addr /* use instead of dev_base to cache pci bus/dev/fn */
hose->cfg_data /* should be the outbound window used for pci cfg  
cycles */
hose->dn->data /* for IMMR regs to tweak window */

thoughts?

Doing this means we should be able to get rid of struct  
mpc83xx_pcie_priv
