This introduces support for EEPROM as a storage for the main Toradex config block and additional config blocks on extra EEPROM chips (on carrier board or video adapters). To enable EEPROM as a storage for the main config block: TDX_HAVE_EEPROM=y. For additional EEPROMs please enable this Kconfig symbol: TDX_CFG_BLOCK_EXTRA=y. Information about existing EEPROM chips is provided via Device Tree using aliases. You can also write configuration for the carrier board using create_carrier subcommand for cfgblock. Example: Verdin iMX8MM # cfgblock create_carrier Supported carrier boards: UNKNOWN CARRIER = [0] Verdin Carrier Board = [1] Choose your carrier board (provide ID): 1 Enter carrier board version (e.g. V1.1B): V1.0A Enter carrier board serial number: 10622780 Also with barcode: Verdin iMX8MM # cfgblock create carrier -y 0156100010622780 Signed-off-by: Igor Opaniuk <igor.opaniuk@toradex.com>

The Toradex config block stored production data on the on-module
|
|
flash device (NAND, NOR or eMMC). The area is normally preserved by
|
|
software and contains the serial number (out of which the MAC
|
|
address is generated) and the exact module type.
