Cover letter [U-Boot] [PATCH v3 0/3] subject: arm: qemu-arm: enable PL031 (RTC)

Virtual Machines provided by qemu for arm are already equipped with RTCdevice (PL031). With this patch set, PL031 driver is converted to driver model and by default enabled on qemu-arm.
It allows us not only to use date command but also to enable UEFI's GetTime/SetTime() services.

This work is motivated by running UEFI SCT(Self-Certification Test) and measuring time. Heinrich has already posted UEFI's GetTime() implementation.

This is a revised version of my proposal[1].
