[U-Boot-Users] RTC for MPC5200

Good morning. I have a couple of questions. After struggling with an initrd
boot for a few days, I said "heck with it" and just made /dev/hda2 my root
device. Given that the kernel is in flash, and the devices I need are
compiled in (and I don't have module support), is there any reason to
mess around with an initrd-style boot, given that we absolutely know
what the hardware config is going to be? It works like a charm with the
default DENX Sys-V init, from the ppc-82xx tree, by the way, though I will
have to prune some services.
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.
Thanks!
