In inteltool.h:
* Can you please briefly explain the need for the macros for {IN,OUT}{B,W,L}
when I don't seen them called from anywhere in the code?

Dropped, thanks.

* If you mean to use them, why are they implemented as macros instead of
functions. I think it'd be easier to read if they were function, and gcc could
possibly even inline such a simple function.

See above.

In inteltool.c:
* Why not just include unistd.h on all platforms?
* I think the #ifdef __FREEBSD__ just makes the code difficult to read. I think
the platform specific code need to be factored out somehow.

* The io_fd variable doesn't appear to be used anywhere after opening the
/dev/io file. Doesn't it need to be closed somewhere? If not, why even bother
creating a variable to hold the value of the open instead of just testing it
directly?

Is this a possible memory leak ? If so, it needs to be fixed in flashrom too.

The Makefile change looks ok.

Thanks,
