+          If you say yes here you get support for the Philips PCF8583
+          RTC chip found on Acorn RiscPCs.  This driver supports the
+          platform specific method of retrieving the current year from
+          the RTC's SRAM.
 
           This driver can also be built as a module. If so, the module
           will be called rtc-pcf8583.
