It's not reliable because a board-id might be shared by multiple models. Note this board-id has no other usage because the manufacturer reused a board-id defined by qcom. We extract some special fields from the label(i.e. ufi001c or uf896) to be the model name for a device, currently it's enough to distinguish between different boards. For example, the label on ufi001c is 'UFI001C_MB_V01', we extract the first field to be the model name.
