-	 * Since the USART supports RS-485 multidrop mode, it allows the
-	 * TX pins to float.  However, for RS-232 operations, we don't want
-	 * these pins to float.  Instead, they should be pulled up to avoid
-	 * mismatches.  Linux does something similar when it configures the
-	 * TX lines.  This implies that we also allow the RX lines to float
-	 * rather than be in the state they are left in by the boot loader.
-	 * Since they are input pins, I think that this is the right thing
-	 * to do.
+	 * Unsure what all is in the HOTe HL200, but I do know there's
+	 * one serial port that isn't DBGU.  There's many other peripherals
+	 * that need to be configured here.
