-/** @file\r
- This module is one template module for Incompatible PCI Device Support protocol.\r
- It includes one incompatile pci devices list template.\r
- \r
- Incompatible PCI Device Support protocol allows the PCI bus driver to support\r
- resource allocation for some PCI devices that do not comply with the PCI Specification.\r
