commit 1faa980cf547d5f03c8cc0c158f4bddd1ab2627a
Author: Timothy Pearson <tpearson at raptorengineeringinc.com>
Date:   Fri Jan 23 20:35:48 2015 -0600

    mainboards: Add support for the Asus KFSN4-DRE series of motherboards
    
    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).
    Video, network, USB, SATA, and serial have received thorough testing.
    
    Known issues:
    RAM initialization is a bit flaky with multiple high-density modules;
    this is probably a generic MCT training issue.
    The XGI Volari option ROM crashes SeaBIOS v1.7.5, but the video device
    works after Linux boots and initializes the device.
    PCIe PME# does not function for an unknown reason, so Wake on Lan is broken.
    Suspend/resume are not yet functional pending additional work on the DSDT.

+ * 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
+====================================================================================================
+
+PCIe slot WAKE# connects to U7 pin E23 (PCIE_WAKE#)
+
+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)
+PU1 pin 37 (VDDPWRGD) drives U7 pin AJ4 (CPU_VLD)
+A small MOSFET directly above another small MOSFET directly above the right-hand edge of the PCIe slot drives U7 pin AK5 (HT_VLD)
+
+When > Barcelona CPU installed on PCB rev 1.04G:
+U7 pin AK4 (MEM_VLD): HIGH
+PU1 pin 37:           LOW
+U7 pin AK5:           LOW
+
+HyperTransport 1.2V supply appears to be generated by a linear regulator containing Q191 and downconverting the CK804 1.5V supply
+The enable pin appears to be tied to AUX_PANEL pin 1 (+5VSB) via a resistor
+Through two MOSFETs the HT supply enable pin is tied to U7 pin AE3 (HTVDD_EN)
