 * We use 2 sets of IDs here, you're free to choose which is which. This

 *
 * Keep the second set NULLed if it should be ignored. Keep the subsystem IDs
 * NULLed if they don't identify the board fully. But please take care to
 * provide an as complete set of pci ids as possible; autodetection is the
 * preferred behaviour and we would like to make sure that matches are unique.
 *
 * The coreboot ids are used two fold. When running with a coreboot firmware,
 * the ids uniquely matches the coreboot board identification string. When a
 * legacy bios is installed and when autodetection is not possible, these ids
 * can be used to identify the board through the -m command line argument.
 *
 * When a board is identified through its coreboot ids (in both cases), the
