Set the environment variable {{filename|baseboard_i2c_enable}} one of the following values to enable the I2C bus of the base board:
* {{parameter|yes}}
* {{parameter|true}} (default)

The variable {{filename|fdtfile}} is updated automatically according to the detected base board:
* SB-SOM: set to {{parameter|imx7d-sbc-imx7.dtb}}.
* SBC-IOT or IOTG: set to {{parameter|imx7d-sbc-iot-imx7.dtb}}.
* Other base board: set to {{parameter|imx7d-cl-som-imx7.dtb}}.
Manual setting of {{filename|fdtfile}} prevents automatic setting.
