You  define  a  list  of  ppc4xx_config_count   known   configuration
settings;  the  data read from the EEPROM either matches one of these
then it is a "known" or "legal" setting, or it does  not  -  in  that
case  the  EEPROM contains an "illegal" setting. This should at least
trigger a warning message (probably including the hex values as  read
from the EEPROM).

Best regards,

Wolfgang Denk
