[ntp:questions] NTP on CubieBoard

On the PC platform, with a recent development ntpd I can achieve
PPS sync with offset within a couple of us on systems in normal
environment, and well within 1us in a temperature conditioned room.

Is this possible on a CubieBoard2 (Allwinner A20 CPU) as well?
Anyone experience with that?  Does the A20 have the required high-res
timestamps and does the Linux kernel for it have kernel-PPS support on a
GPIO pin?
