- Add PCI Extended Configuration Space support into x86. - Check register offset of pci_conf_read() in MD part. It returns (pcireg_t)-1 if it isn't accessible. - Decode Extended Capability in PCI Extended Configuration Space. Currently the following extended capabilities are decoded: - Advanced Error Reporting - Virtual Channel - Device Serial Number - Power Budgeting - Root Complex Link Declaration - Root Complex Event Collector Association - Access Control Services - Alternative Routing-ID Interpretation - Address Translation Services - Single Root IO Virtualization - Page Request - TPH Requester - Latency Tolerance Reporting - Secondary PCI Express - Process Address Space ID - LN Requester - L1 PM Substates The following extended capabilities are not decoded yet: - Root Complex Internal Link Control - Multi-Function Virtual Channel - RCRB Header - Vendor Unique - Configuration Access Correction - Multiple Root IO Virtualization - Multicast - Resizable BAR - Dynamic Power Allocation - Protocol Multiplexing - Downstream Port Containment - Precision Time Management - M-PCIe - Function Reading Status Queueing - Readiness Time Reporting - Designated Vendor-Specific
