commit c02ad5968181d692c7e16f5900f5cf5fbb38b2a5 Author: Teo Boon Tiong boon.tiong.teo@intel.com Date: Mon Sep 5 16:00:07 2016 +0800
superio/nuvoton: Add back Nuvoton NCT6776 support
Revert commit 53552cc0 (Drop SuperIO nuvoton/nct6776), removing the code as no other mainboard uses it.
The board Intel Saddle Brook uses this device, so add the code back with minor adaptations.
