+ When enabled, additional eeprom sub-commands become available.
+
+ eeprom print - prints the contents of the eeprom in a human-readable
+ way (eeprom layout fields, and data formatted to be fit for human
+ consumption).
+
+ eeprom update - 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.
+
+ 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.
