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.
