[U-Boot] [PATCH v4 0/2] arm: qemu-arm: enable PL031 (RTC)

[Akashi, Takahiro]

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].

* use readl/writel() instead of private macros
* add a debug message to pl031_rtc_set()
* remove CONFIG_SYS_RTC_PL031_BASE from config_whitelist.txt
