toradex: tdx-cfg-block: add support for EEPROM
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 provide 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:
cVerdin iMX8MM # cfgblock create carrier -y 0156100010622780
