   This file declares EFI Incompatible PCI Device Support Protocol

+  This protocol allows the PCI bus driver to support resource allocation for some PCI devices that do not comply

+  with the PCI Specification.

+  The EFI_INCOMPATIBLE_PCI_DEVICE_SUPPORT_PROTOCOL is used by the PCI bus driver

+  to support resource allocation for some PCI devices that do not comply with the PCI Specification.

+  This protocol can find some incompatible PCI devices and report their special resource

+  requirements to the PCI bus driver. The generic PCI bus driver does not have prior knowledge of

+  any incompatible PCI devices. It interfaces with the

+  EFI_INCOMPATIBLE_PCI_DEVICE_SUPPORT_PROTOCOL to find out if a device is

+  incompatible and to obtain the special configuration requirements for a specific incompatible PCI

+  device.

+  This protocol is optional, and only one instance of this protocol can be present in the system. If a

+  platform supports this protocol, this protocol is produced by a Driver Execution Environment

+  (DXE) driver and must be made available before the Boot Device Selection (BDS) phase. The PCI

+  bus driver will look for the presence of this protocol before it begins PCI enumeration.
