With this patch, PL031 driver is converted to driver-model-compliant driver. In addition, CONFIG_SYS_RTC_PL031_BASE is no longer valid.

Enable ARM PL031 driver.
Tom merged http://git.denx.de/?p=u-boot.git;a=commit;h=b19886b9469174213877ef37670ce35c... https://patchwork.ozlabs.org/patch/936533/ ARM: qemu-arm: enable RTC which is superseeded by your patch series.
We should avoid duplicate entries CONFIG_RTC_PL031.
Symbol CONFIG_SYS_RTC_PL031_BASE can be removed in include/configs/qemu-arm.h with this patch.
Could you, please, respin your patch series.
Best regards
Heinrich
