mainboards: Add support for the Asus KFSN4-DRE series of motherboards

Hardware / Coreboot - Timothy Pearson [raptorengineeringinc.com] - 28 January 2015 15:12 UTC

Status: Tested with KFSN4-DRE PCB v1.04G Booted Ubuntu Linux 14.04 and all onboard peripherals appear to work. Dual Opteron 8347 CPUs tested with 8GB RAM (4GB per bank). Dual Opteron 8356 CPUs tested with 1GB RAM in slot A1. AMD PowerNow! functions correctly via ACPI.
Video, network, USB, SATA, and serial have received thorough testing. Tested with KFSN4-DRE PCB v1.05G Single Opteron 2419 CPU tested with 1GB RAM in slot A1. Booted to PXE configuration menu; not tested further.

Known issues: RAM initialization is a bit flaky with multiple high-density modules; this could be a generic MCT training issue but is probably bad hardware. The XGI Volari option ROM crashes SeaBIOS v1.7.5, but the video device works after Linux boots and initializes the device. Suspend/resume functions at the S1 level but sometimes hangs on resume. Wake on LAN can be flaky; the strap(s) needed to have WoL work on power application were not physically installed by ASUS so the board needs to boot at least once after power application before it will work.
