As get_time_ns() is one of the most called function of barebox at runtime.

2012-10-29	cf16704 Browse files » clock: introduce non interruptible timeout ... is_timeout call poller_call if the timeout is >= 100us but on 1-wire bus we need to wait 500us and not more than 930us for the bus reset. So if the poller_call is caller we can not guarantee it. So for this introduce is_non_interruptible_timeout than we only wait. Use it for ndelay too.

2008-06-05	eb208c7 Browse files » 002-clock-overflow ... [Patch 02/17] U-Boot-V2: Handle case of clock rollover for get_time_ns get_time_ns does a simplistic delta = cycle_now - cycle_last. It is possible that the h/w counter reached max and reset back to 0. This patch addresses this issue by checking for rollover condition. NOTE 1: This does not guarentee that you cannot confuse get_time_ns. You could possibly wait for two reset cycles and then get a messed up value. To fix that we may need interrupt mode timer tick - something on the lines of jiffies on linux. NOTE 2: the question of cs->mask is not clear. if the mask is for the tick, then it is better done with (cycle_now & cs->mask) - (cs->cycle_last & cs->mask).
