Module Name:

  GenFvImageExe.c

Abstract:

  This contains all code necessary to build the GenFvImage.exe utility.       
  This utility relies heavily on the GenFvImage Lib.  Definitions for both
  can be found in the Tiano Firmware Volume Generation Utility 
  Specification, review draft.

Routine Description:

  This utility uses GenFvImage.Lib to build a firmware volume image.

Arguments:

  FvInfFileName      The name of an FV image description file.

  Arguments come in pair in any order.
    -I FvInfFileName 

Returns:

  EFI_SUCCESS            No error conditions detected.
  EFI_INVALID_PARAMETER  One or more of the input parameters is invalid.
  EFI_OUT_OF_RESOURCES   A resource required by the utility was unavailable.  
                         Most commonly this will be memory allocation 
                         or file creation.
  EFI_LOAD_ERROR         GenFvImage.lib could not be loaded.
  EFI_ABORTED            Error executing the GenFvImage lib.
