Multiple different boards share the same values. Only the original reference designs can currently be identified and loaded from the board-2.bin. But these will not result in the correct calibration data when combined with the pre-calibration data from the device. An additional "variant" information has to be provided to select the correct board data for a design which was modified by an ODM. This follows the same approach as ath10k.
