BTW, I've committed changes for mk48t02 drivers on newsmips port
to use the MI mk48txx(4) driver and todr(9) APIs.

If you are trying -current on news3400 (i.e HB based machines),
you have to update entries for mkclock on hb0 in your kernel
config files like this:

-mkclock0 at hb0 addr 0xbff407f8		# MK48T02 realtime clock
+mkclock0 at hb0 addr 0xbff40000		# MK48T02 realtime clock

(No change is needed for AP-bus based (news5000) system.)

As mentioned above, MK48T02 clock on news3400 is located
at addr 0xbff00000 and offset to its control register is 0x7f8.
(see also src/sys/dev/ic/mk48txx.c and mk48txxreg.h)

But I think it's much easier to change date by date(1) command on OS.
