Fix flashrom running on boards with coreboot
In r1577 we removed the discrimination of coreboot IDs and user-specified mainboards. The problem is that the board enable code required to find a board enable if either of these model strings were set. Therefore boards running coreboot that do not need a board enable failed to execute flashrom since then. This patch fixes this by handling coreboot IDs and user-supplied IDs differently again. Corresponding to flashrom svn r1605. Signed-off-by: Stefan Tauner <stefan.tauner@alumni.tuwien.ac.at> Acked-by: Idwer Vollering <vidwer@gmail.com>
