[PATCH] powerpc: properly configure DDR/P5IOC children devs
The dynamic add path for PCI Host Bridges can fail to configure children adapters under P5IOC controllers. It fails to properly fixup bus/device resources, and it fails to properly enable EEH. Both of these steps need to occur before any children devices are enabled in pci_bus_add_devices(). Signed-off-by: John Rose <johnrose@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
