cmd: eeprom: add support for layout aware commands
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.
