PCI: support for PCI Express fundamental reset
This is the first of three patches that implement a bit field that PCI
Express device drivers can use to indicate they need a fundamental reset
during error recovery.
By default, the EEH framework on powerpc does what's known as a "hot
reset" during recovery of a PCI Express device. We've found a case
where the device needs a "fundamental reset" to recover properly. The
current PCI error recovery and EEH frameworks do not support this
distinction.
The attached patch (courtesy of Richard Lary) adds a bit field to
pci_dev that indicates whether the device requires a fundamental reset
during recovery.
These patches supersede the previously submitted patch that implemented
a fundamental reset bit field.
