libpci defines an arbitrary set of PCI vendor IDs, flashrom uses the Intel definition. Add it. flashrom also requires inttypes.h, so add the OpenBSD version Change-Id: I9bffd8193f635c375ac4d6b6eae8d3d876b95f5f Signed-off-by: Patrick Georgi <patrick.georgi@secunet.com> Reviewed-on: http://review.coreboot.org/154 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
