+          Enables drivers for the Real-Time Clock battery-backed chips on
+          some products. The kernel reads the time when booting, and
+          the date can be set using ioctl(fd, RTC_SET_TIME, &rt) with rt a
+          rtc_time struct (see <file:include/asm-cris/rtc.h>) on the /dev/rtc
+          device.  You can check the time with cat /proc/rtc, but
+          normal time reading should be done using libc function time and
+          friends.
