xupv2p support generates MAC addresses based on a silicon serial ID.
General reminder, no new code will be accepted in arch/ppc.  It's in
bugfix state only.

I of course have no problems with people sending patches for new stuff,
but I don't want people to get the idea that it will wind up in tree.

+#include <linux/xilinx_devices.h>
+#include <platforms/4xx/xparameters/xparameters.h>
+
+int virtex_device_fixup(struct platform_device *dev)
Could this be a static function?
+{
+#ifdef XPAR_ONEWIRE_0_BASEADDR
+	int i;
+	// Use the Silicon Serial ID attached on the onewire bus to
+	// generate sensible MAC addresses.
No C++ style comments please.
+	unsigned char *p_onewire = ioremap(XPAR_ONEWIRE_0_BASEADDR, 6);
What happens if ioremap fails?
+	struct xemac_platform_data *pdata = dev->dev.platform_data;
+	if (strcmp(dev->name, "xilinx_emac") == 0) {
+		printk(KERN_INFO "Fixup MAC address for %s:%d\n",
+		       dev->name, dev->id);
+		// FIXME.. this doesn't seem to return data that is consistent
+		// with the self test... why not?
+		pdata->mac_addr[0] = 0x00;
+		pdata->mac_addr[1] = 0x0A;
+		pdata->mac_addr[2] = 0x35;
+		pdata->mac_addr[3] = dev->id;
+		pdata->mac_addr[4] = p_onewire[4];
+		pdata->mac_addr[5] = p_onewire[5];
+		pr_debug(KERN_INFO
+			 "MAC address is now %2x:%2x:%2x:%2x:%2x:%2x\n",
+			 pdata->mac_addr[0], pdata->mac_addr[1],
+			 pdata->mac_addr[2], pdata->mac_addr[3],
+			 pdata->mac_addr[4], pdata->mac_addr[5]);
+	}
+	iounmap(p_onewire);
+#endif
+	return 0;
+}
