* Below is the list of boards which need a special "board enable" code in
* flashrom before their ROM chip can be accessed/written to.
*
* NOTE: Please add boards that _don't_ need such enables or don't work yet
* to the respective tables in print.c. Thanks!
*
* We use 2 sets of IDs here, you're free to choose which is which. This
* is to provide a very high degree of certainty when matching a board on
* the basis of subsystem/card IDs. As not every vendor handles
* 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 and if you can't use DMI.
* 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.
*
* If PCI IDs are not sufficient for board matching, the match can be further
* constrained by a string that has to be present in the DMI database for
* the baseboard or the system entry. The pattern is matched by case sensitve
* substring match, unless it is anchored to the beginning (with a ^ in front)
* or the end (with a $ at the end). Both anchors may be specified at the
* same time to match the full field.
*
* When a board is matched through DMI, the first and second main PCI IDs
* and the first subsystem PCI ID have to match as well. If you specify the
* first subsystem ID as 0x0:0x0, the DMI matching code expects that the
* subsystem ID of that device is indeed zero.
*
* 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.
