541**  \brief EEPROM fixup code for INI values
542**
543** This routine provides a place to insert "fixup" code for specific devices
544** that need to modify INI values based on EEPROM values, BEFORE the INI values
545** are written.
546** Certain registers in the INI file can only be written once without
547** undesired side effects, and this provides a place for EEPROM overrides
548** in these cases.
549**
550** This is called at attach time once.  It should not affect run time
551** performance at all
552**
553**  \param ah       Pointer to HAL object (this)
554**  \param p_eep_data Pointer to (filled in) eeprom data structure
555**  \param reg      register being inspected on this call
556**  \param value    value in INI file
557**
558**  \return Updated value for INI file.
