/*++
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.

Returns:
EFI_SUCCESS - RomImage is valid.
