Hi,
Our SoC using ppc440 core will run on an emulator first. It doesn't
have an external RTC. Hence time_init, set_rtc_time, get_rtc_time of
ppc_md are all set to NULL. No TODC_ALLOC() is defined.
I'm wondering if todc is vital to make OS run correctly. Is there any
other choice?
I grepped ppc_md.time_init in the kernel source. It seems that linux
can run without ppc_md.time_init.
Any ideas?
-Shawn.

No, RTC isn't required for Linux to run, but usually is useful to
have.
