* 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.
