commit 66bbf3a5db985bcb5ebfd4d9b9de3f7fff659f48
Author: Timothy Pearson <tpearson at raptorengineeringinc.com>
Date:   Fri Jan 23 20:35:48 2015 -0600

    Add support for the Asus KFSN4-DRE series of motherboards
    
    Status:
    All onboard peripherals appear to work
    Dual quad-core CPUs tested with 8GB RAM (4GB per bank)
    Video, network, USB, SATA, and serial have received thorough testing
    
    Known issues:
    RAM initialization is a bit flaky with multiple high-density modules (likely an AGESA problem)
    The XGI Volari video BIOS crashes SeaBIOS, but the video device works after Linux boots
    PCIe PME# does not function for an unknown reason, so Wake on Lan is broken
    
    Note that this patch requires the previous 12 patches or the mainboard won't POST

+ * BOOL AMD_CB_ManualBUIDSwapList(u8 Node, u8 Link, u8 **List)
+ * Description:
+ *	This routine is called every time a non-coherent chain is processed.
+ *	BUID assignment may be controlled explicitly on a non-coherent chain. Provide a
+ *	swap list. The first part of the list controls the BUID assignment and the
+ *	second part of the list provides the device to device linking.  Device orientation
+ *	can be detected automatically, or explicitly.  See documentation for more details.
+ *
+ *	Automatic non-coherent init assigns BUIDs starting at 1 and incrementing sequentially
+ *	based on each device's unit count.
+ *
+ * Parameters:
+ *	@param[in]  node   = The node on which this chain is located
+ *	@param[in]  link   = The link on the host for this chain
+ *	@param[out] List   = supply a pointer to a list

+
+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
+
+====================================================================================================
+Other hardware
+====================================================================================================
+
+CPU_WARN1 is driven by (???) via a simple buffer (U13 pin 10)
+MEM_WARN1 is driven by U7 pin AD3 (CPUVDD_EN) via a simple buffer (U101 pin 3)
+
+U7 pin AK3 is disconnected (routed to unpopulated capacitor/resistor)
