[PATCH] ppc64: Save & restore of PCI device BARS
14-eeh-device-bar-save.patch
After a PCI device has been resest, the device BAR's and other config
space info must be restored to the same state as they were in when
the firmware first handed us this device. This will allow the
PCI device driver, when restarted, to correctly recognize and set up
the device.
Tis patch saves the device config space as early as reasonable after
the firmware has handed over the device. Te state resore funcion
is inteded for use by the EEH recovery routines.
