Syntax:= eepromtool <option>
  Display help-text:=
      eepromtool --help                                         (or)
      eepromtool -h
  List the understood TLV codes and names:=
      eepromtool --list                                         (or)
      eepromtool -l
  List all eeprom devices:=
      eepromtool --listdevices                                  (or)
      eepromtool -L
  Dump the PSU eeprom:=
      eepromtool --psueepromdump                                (or)
      eepromtool -m
  Dump the FAN eeprom:=
      eepromtool --faneepromdump                                (or)
      eepromtool -F
  Show the EEPROM data:=
     eepromtool --eeprom=<eepromtype> --show                    (or)
     eepromtool -P <eepromtype>  -x
  Reset the EEPROM data:=
     eepromtool --eeprom=<eepromtype> --erase                   (or)
     eepromtool -P <eepromtype>  -e
  Verify the MAC address in system-eeprom and mac-eeprom:=
     eepromtool --eeprom=<eepromtype> --test                    (or)
     eepromtool -P <eepromtype>  -t
  Look up a TLV by code and write the value to stdout:=
     eepromtool --eeprom=<eepromtype> --get <code>              (or)
     eepromtool -P <eepromtype>  -g <code>
  Execute repeatedly command by count:=
     eepromtool --iteration=max/<count> [option1] [option2]...  (or)
     eepromtool -I max/<count> [option1] [option2]...
  Set a TLV code to a value:=
     eepromtool --eeprom=<eepromtype> --set <code>=<value>,<code>=<value>...(or)
     eepromtool -P <eepromtype> -s <code>=<value>,<code>=<value>...

Usage:=
    -h, --h              Show the help text
    -l, --list           List the understood TLV codes and names
    -L, --listdevices    List all EEPROM devices
    -m, --psueepromdump  Dump the PSU EEPROM
    -F, --faneepromdump  Dump the FAN EEPROM
    -P, --eeprom=        EEPROM type
    -x, --show           Show operation
    -e, --erase          Erase operation
    -t, --test           Test using the pre-programmed configuration or use supplied config
    -I, --iteration=     Iteration command execution
    -g, --get            Get operation
    -s, --set            Set operation
