Routine Description:
This utility uses GenFvImage.Lib to build a firmware volume image.
Arguments:
FvInfFileName The name of an FV image description file or Capsule Image.
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.
