Author: hailfinger Date: Fri Jul 2 19:12:50 2010 New Revision: 1067 URL: http://flashrom.org/trac/coreboot/changeset/1067
Log: Add OpenBSD support. Add a requirements section to the man page which lists the needed access permissions for each programmer.
This feature needs my pciutils/libpci 8/16-bit write emulation patch at http://marc.info/?l=openbsd-ports&m=127780030728045 titled [PATCH] Fix pciutils non-32bit PCI write on OpenBSD
