commit f623ea13054c908f61bc8f5dd0bc218c439352ba
Author: Timothy Pearson <tpearson at raptorengineeringinc.com>
Date:   Wed Oct 28 02:59:40 2015 -0500

    mainboard: Add initial K8-compatible version of the KFSN4-DRE
    
    This is a clone of the original Family 10h-compatible ASUS
    KFSN4-DRE board, modified for basic K8 support to allow for
    future K8 Socket F Opteron testing.
    
    TEST: Booted KFSN4-DRE with 1 Opteron 8222 processor
    
    KNOWN ISSUES:
     * Second CPU package fails to initialize AP
       This prevents use of a secondary CPU package
     * Second memory channel of at least CPU package #0
       does not function (crash at CAR handoff)

+DIMM_A1 SDA signal traced to U6 pin 1
+Destructive testing of failed board (removal of U7 northbridge!) yielded the following information:
+U6 S0 <--> U7 W2
+U6 S1 <--> U7 W3
+
+Proprietary BIOS enables the SPD during POST with:
+S0: LOW
+S1: LOW
+
+then temporarily switches to:
+S0: LOW
+S1: HIGH
+
+then switches to runtime mode with:
+S0: HIGH
+S1: LOW

+After probing with a custom GPIO-flipping tool under Linux the following GPIO mappings were found:
+CK804 pin W2 <--> GPIO43
+CK804 pin W3 <--> GPIO44
