  )
/*++

Routine Description:

  Update the Firmware Volume Buffer with requested buffer data
  
Arguments:

  StartAddress   - StartAddress in buffer. This number will automatically
                  point to right address in buffer where data needed 
                  to be updated.
  Buffer         - Buffer pointer from data will be copied to memory mapped buffer.
  DataSize       - Size of the data needed to be copied.
  LocType        - The type of the VTF

Returns:
  
  EFI_ABORTED  - The input parameter is error
  EFI_SUCCESS  - The function completed successfully

/*++

Routine Description:

  This function adds the SYM tokens in the source file to the destination file.
  The SYM tokens are updated to reflect the base address.

Arguments:

  BaseAddress    - The base address for the new SYM tokens.
  DestFileName   - The destination file.
  SourceFileName - The source file.
  FileSize       - Size of bin file.

Returns:

  )
/*++
  
Routine Description:

  This function will perform byte checksum on the FIT table, if the the checksum required
  field is set to CheckSum required. If the checksum is not required then checksum byte
  will have value as 0;.
  
Arguments:

  NONE
  
Returns:

  Status       - Value returned by call to CalculateChecksum8 ()
  EFI_SUCCESS  - The function completed successfully

  IN  FILE    *fp
  )
/*++

Routine Description:

  This is the main function which will be called from application.

Arguments:

  StartAddress1  - The start address of the first VTF      
  Size1          - The size of the first VTF
  StartAddress2  - The start address of the second VTF      
  Size2          - The size of the second VTF

Returns:
 
  EFI_OUT_OF_RESOURCES - Can not allocate memory
  The return value can be any of the values 
  returned by the calls to following functions:
      GetVtfRelatedInfoFromInfFile
