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.
