  • aa9e60441   cmd: eeprom: add support for layout aware commands ... Browse Code ยป

    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.
