[flashrom] Porting flashrom to OpenBSD

[Carl-Daniel Hailfinger]

Hi Jonathan,

you're in CC of this mail because you sent the "unbreak pciutils" mail
to this list, and the failure mode is related.

Right, my bad. Thanks.

Excerpt from that log:

Ouch. I remember a pciutils patch on the ports mailing list which may be
related to this: http://marc.info/?l=openbsd-ports&m=126918139214769
flashrom uses libpci from pciutils, and it absolutely _must_ have write
access to PCI.

Thanks, looks good. One small comment about installation in sbin,
though. flashrom can also work with programmers attached to serial ports
and USB, and those might work even for non-root users if appropriate
permissions are set (well, under most Unix-like OS, but OpenBSD might be
different). Due to that, some people think installing in bin instead of
sbin makes more sense.

Stuart, does the pcilib abort happen on i386 and amd64?

Carl-Daniel
