/**
  Perform flash write operation with progress indicator.  The start and end
  completion percentage values are passed into this function.  If the requested
  flash write operation is broken up, then completion percentage between the
  start and end values may be passed to the provided Progress function.  The
  caller of this function is required to call the Progress function for the
  start and end completion percentage values.  This allows the Progress,
  StartPercentage, and EndPercentage parameters to be ignored if the requested
  flash write operation can not be broken up

  @param[in] Length            The length of data buffer in bytes.
  @param[in] Progress          A function used report the progress of the

                               that may be NULL.
  @param[in] StartPercentage   The start completion percentage value that may
                               be used to report progress during the flash
                               write operation.
  @param[in] EndPercentage     The end completion percentage value that may
