TODC on ppc440

[Shawn Jin]

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?
