What good is a RTC that has no separate backup power pin?
It will only keep running as long as main power is applied to the 5200. Of course you can minimise power consumption by shutting down everything in the 5200, but still you will not have a real RTC with GoldCap or Lithium Battery.

The other question regards the real time clock on the MPC5200. Unless I
am
seriously overlooking something, this does not appear to be implemented,
yet,
yes? The register structure doesn't look too arcane. Is anybody working
on
this? I am tempted, but nobody wants to roll in code from a rank novice.
The
project we're working on needs a self-contained clock. I notice that
u-boot
provides rtc services, but isn't that more properly a kernel function?
I'm
a little fuzzy on the dividing line.
