mainboard that we learned with the serengeti that we needed. New function in pnp that is for reading. new prototype in pnp.h. New constants for ite8716f. This board does not build yet; we are exercising code in k8 north that the serengeti did not enable. More tomorrow. Now that we have two boards under way we can hopefully see our way to getting more put in. The 690 is the obvious next choice. Signed-off-by: Ronald G.
