QEMU provides an emulated ARM AMBA PrimeCell PL031 RTC. The patch sets the base address in the board include file according to the definition in hw/arm/virt.c of the QEMU source. It defines the Kconfig option for the existing driver, and enables the RTC driver in qemu_arm64_defconfig and qemu_arm_defconfig as well as the date command. We need an RTC to provide the GetTime() runtime service in the UEFI subsystem.
