Linking in support for the internal programmer doesn't make sense if you only need hardware (ioport, memory) access. Note: This patch was created by "svn cp internal.c hwaccess.c" and then removing stuff from both files. That's why you can't apply the patch as-is before running the svn cp. Corresponding to flashrom svn r898. Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Acked-by: Sean Nelson <audiohacked@gmail.com>
