The Board ID of a device (also known as BORD, BDID, or ApBoardId) is a value (usually represented as uint8_t) that represents multiple characteristics of the logic board. In a BuildManifest, this value is found in the ApBoardId tag. The characteristics represented by a given Board ID may be specific to the SoC.
