* arch/arm/src/sama5/chip/sam_gpbr.h: Add SAMA5 GPBR register
definitions (2013-10-19).
* Kconfig: Add support for CONFIG_DEBUG_RTC (2013-10-19).
* configs/sama5d3x-ek/README.txt, demo/defconfig: Describe how to
enable RTC support for the nsh/ configuration; RTC is now enabled by
default in the demo configuration (2013-10-19).
