Routine Description:
The PlatformNotify() function can be used to notify the platform driver so that
it can perform platform-specific actions. No specific actions are required.
Eight 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 Phase-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 handle of the host bridge controller.
Phase - The phase of the PCI bus enumeration.
ChipsetPhase - Defines the execution phase of the PCI chipset driver.
Returns:
EFI_SUCCESS - The function completed successfully.

Routine Description:
The GetPlatformPolicy() function retrieves the platform policy regarding PCI
enumeration. The PCI bus driver and the PCI Host Bridge Resource Allocation Protocol
driver can call this member function to retrieve the policy.
Arguments:

PciPolicy - The platform policy with respect to VGA and ISA aliasing.
Returns:

/*++
Routine Description:
The GetPciRom() function gets the PCI device's option ROM from a platform-specific location.
The option ROM will be loaded into memory. This member function is used to return an image
that is packaged as a PCI 2.2 option ROM. The image may contain both legacy and EFI option
ROMs. See the EFI 1.10 Specification for details. This member function can be used to return
option ROM images for embedded controllers. Option ROMs for embedded controllers are typically
stored in platform-specific storage, and this member function can retrieve it from that storage
and return it to the PCI bus driver. The PCI bus driver will call this member function before
scanning the ROM that is attached to any controller, which allows a platform to specify a ROM
image that is different from the ROM image on a PCI card.
Arguments:
This - Pointer to the EFI_PCI_PLATFORM_PROTOCOL instance.
PciHandle - The handle of the PCI device.
RomImage - If the call succeeds, the pointer to the pointer to the option ROM image.
Otherwise, this field is undefined. The memory for RomImage is allocated
by EFI_PCI_PLATFORM_PROTOCOL.GetPciRom() using the EFI Boot Service AllocatePool().
It is the caller's responsibility to free the memory using the EFI Boot Service
FreePool(), when the caller is done with the option ROM.
RomSize - If the call succeeds, a pointer to the size of the option ROM size. Otherwise,
this field is undefined.
Returns:
EFI_SUCCESS - The option ROM was available for this device and loaded into memory.
EFI_NOT_FOUND - No option ROM was available for this device.
EFI_OUT_OF_RESOURCES - No memory was available to load the option ROM.
EFI_DEVICE_ERROR - An error occurred in getting the option ROM.
