      cmd: eeprom: add support for layout aware commands · aa9e6044
      Nikita Kiryanov authored
      Introduce the (optional) eeprom print and eeprom update commands.
      
      These commands are eeprom layout aware:
      * The eeprom print command prints the contents of the eeprom in a human
        readable way (eeprom layout fields, and data formatted to be fit for human
        consumption).
      * The eeprom update command allows user to update eeprom fields by specifying
        the field name, and providing the new data in a human readable format (same
        format as displayed by the eeprom print command).
      * Both commands can either auto detect the layout, or be told which layout to
        use.
      
      New CONFIG options:
      CONFIG_CMD_EEPROM_LAYOUT - enables commands.
      CONFIG_EEPROM_LAYOUT_HELP_STRING - tells user what layout names are supported
      
      Feature API:
      __weak int parse_layout_version(char *str)
      	- override to provide your own layout name parsing
      __weak void __eeprom_layout_assign(struct eeprom_layout *layout, int layout_version);
      	- override to setup the layout metadata based on the version
      __weak int eeprom_layout_detect(unsigned char *data)
      	- override to provide your own algorithm for detecting layout version
      eeprom_field.c
      	- contains various printing and updating functions for common types of
      	  eeprom fields. Can be used for defining custom layouts.
