            The MCF52xx I2C driver can support multiple I2C bus devices, but
          typically the coldfire processor only provides a single device. By
          default the driver assumes only a single device is present and will
          optimize for that case, using constant definitions provided by the
          platform HAL rather than per-device structure fields. If the hardware
          has multiple I2C bus devices, or if a singleton bus is instantiated
          by some other package and hence the platform HAL cannot provide the
          necessary definitions, then this option should be enabled."
