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

* subsystem/card IDs in a sane manner.
*
* 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
* main pci ids are still required to match, as a safeguard.
