hwclock expects a standard /dev/rtc interface, which is not available
for the MPC8xx in some versions of the Linux kernel.
If you're looking for an implementation, check out our kernel

How many seconds are there in a year? If I tell you there are 3.155 x
10^7, you won't even try to remember it. On the other hand, who could
forget that, to within half a percent, pi seconds is a nanocentury.
