Hi.
I am study the time of the arm , I have a question:
In the \arm\kernel\times.c . there is a function pointer int
(*set_rtc)(void).it is the hook for setting the RTC's idea of the current
time. but I can't find which function to this pointer. somebody can tell me
where I can find it and how to set the RTC. thanks!

It's never set in today's kernels, because it's redundant. RTCs should
instead be implemented using the RTC support code in drivers/rtc, which
will take care of all this for you.
