+/*++
+
+Routine Description:
+
+ The PlatformPrepController() function can be used to notify the platform driver so that
+ it can perform platform-specific actions. No specific actions are required.
+ Several notification points are defined at this time. More synchronization points may be
+ added as required in the future. The PCI bus driver calls the platform driver twice for
+ every PCI controller-once before the PCI Host Bridge Resource Allocation Protocol driver
+ is notified, and once after the PCI Host Bridge Resource Allocation Protocol driver has
+ been notified.
+ This member function may not perform any error checking on the input parameters. It also
+ does not return any error codes. If this member function detects any error condition, it
+ needs to handle those errors on its own because there is no way to surface any errors to
+ the caller.
+
+Arguments:
+
+ This - Pointer to the EFI_PCI_PLATFORM_PROTOCOL instance.
+ HostBridge - The associated PCI host bridge handle.
+ RootBridge - The associated PCI root bridge handle.
+ PciAddress - The address of the PCI device on the PCI bus.
+ Phase - The phase of the PCI controller enumeration.
+ ChipsetPhase - Defines the execution phase of the PCI chipset driver.
+
+Returns:
+
+ EFI_SUCCESS - The function completed successfully.
+ EFI_UNSUPPORTED - Not supported.
