This is a revised version of my proposal[1].
[1] https://lists.denx.de/pipermail/u-boot/2018-July/333534.html
VMs provided by qemu for arm are equiped with PL031 device. In patch#1, pl031 driver is converted to driver model, and in patch#2, this driver is enabled in defconfig of qemu-arm.
This patch set is motivated by running UEFI SCT(Self-Certification Test) and measuring time on u-boot on qemu-arm. Heinrich has already posted UEFI's GetTime() implementation.
Changes in v2(July 4, 2018) * based on Heinrich's comments, * remove legacy mode interface * enable the driver in defconfig
