On many recent Chrome OS boards, the desire to unite more configurations under the same image has led to the need of a "SKU ID" that identifies different configurations of the same board (e.g. with certain optional components stuffed or not stuffed, or replaced with a comparable component). This is markedly different from the existing "board ID", because that is reserved to count "revisions" -- changes made to the same configuration over time during the development process. This patch adds support to have a mainboard define this SKU ID and pass it through the coreboot table like we already have for board IDs.
