+ * 1. Probe driver for the Malta's UART ports:
  *
  *   o 2 ports in the SMC SuperIO
  *   o 1 port in the CBUS UART, a discrete 16550 which normally is only used
  *
  * We don't use 8250_platform.c on Malta as it would result in the CBUS
  * UART becoming ttyS0.
+ *
+ * 2. Register RTC-CMOS platform device on Malta.
