[flashrom] [PATCH] new windows port

Hi,
we've been getting multiple requests for PCI-based programmer support on
Windows, and now that internal programmer support is optional and a few
other architectural cleanups were done, Windows support for anything
using PCI should be easier to merge.

Yes, that would be nice.
In case anyone wants to take a look at directio.h in split up form, I've
inlined a patch for reference. This makes it a bit easier to see what
directio.h provides besides PCI #defines.
Regards,
Carl-Daniel
