Robert,

I have already added the hostbridge for family15h in this patch.

+static struct amd_hostbridge hb_probes[] __initdata = {
+	{ 0, 0x18, 0x1100 }, /* K8 */
+	{ 0, 0x18, 0x1200 }, /* Family10h */
+	{ 0xff, 0, 0x1200 }, /* Family10h */
+	{ 0, 0x18, 0x1300 }, /* Family11h */
+	{ 0, 0x18, 0x1600 }, /* Family15h */ <--- HERE
  };

The rest of the changes are mostly comments, some minor renaming of 
variables for clarity, and replace hardcode values with preprocessor 
macro.  If needed, I can split them.
