Routine Description:

  Relocate runtime images.

Arguments:

  Image   - Points to the relocation data of the image.

Returns:

  None.

/*++

Routine Description:

  Performs Processor specific relocation fixup

Arguments:

  Reloc      - Pointer to the relocation record
  Fixup      - Pointer to the address to fix up
  FixupData  - Pointer to a buffer to log the fixups
  Adjust     - The offset to adjust the fixup

Returns:

Routine Description:

  Calculate CRC32 for target data

Arguments:

  Data     - The target data.
  DataSize - The target data size.
  CrcOut   - The CRC32 for target data.

Returns:

  EFI_SUCCESS           - The CRC32 for target data is calculated successfully.
  EFI_INVALID_PARAMETER - Some parameter is not valid, so the CRC32 is not 
                          calculated.

Routine Description:

  Determines the new virtual address that is to be used on subsequent memory accesses.

Arguments:
  
  DebugDisposition    - Supplies type information for the pointer being converted.
  ConvertAddress      - A pointer to a pointer that is to be fixed to be the value needed
                        for the new virtual address mappings being applied.

Returns:

  EFI_SUCCESS             - The pointer pointed to by Address was modified.
  EFI_NOT_FOUND           - The pointer pointed to by Address was not found to be part
                            of the current memory map. This is normally fatal.
  EFI_INVALID_PARAMETER   - One of the parameters has an invalid value.

Routine Description:

  Install Runtime AP. This code includes the EfiRuntimeLib, but it only 
  functions at RT in physical mode. 

Arguments:
  
  ImageHandle   - Image handle of this driver.
  SystemTable   - Pointer to the EFI System Table.

Returns:

  EFI_SUCEESS - Runtime Driver Architectural Protocol installed.
