if you compare the datasheets, you'll see that it's incompatible with
the 9series PCH.

I'm currently working on upstream support for the Sunrise Point PCH [1].
It's not working yet on my system. But if you want to try it out / help
me debugging remaining issues, here's how you can fetch the code:

  $ git clone https://review.coreboot.org/flashrom
  $ cd flashrom
  $ git fetch https://review.coreboot.org/flashrom
refs/changes/40/18940/1 && git checkout FETCH_HEAD

You'd still have to set your chipset to NT instead of BAD in
chipset_enable.c.

Nico

PS. You can also try the chromiumos fork of flashrom (can't give you
    build instructions though).
