hmmm it's working partly, it seems. First i did something wrong that skrewed up the com port setup, which I fixed. I now get the debug messages I added via the serial line, but, strangely, only when i do a (warm) reboot from a running linux, not with a cold boot... probably something needs to be set that doesn't get set by default on cold reboot.
Not good. Can you send me a copy of your tree or a patch, and a complete boot log? I've seen the same issue, I just can't remember how I fixed it at the moment. It's something to do with either the romcc build parameters or failover code, I can't remember atm. Also, vt8601 is compatible with both c3 and p2/p3, right? Which are you using?
Anyway, it's the SMBus controller where things go wrong; the log says:
SMBUS controller not found
Check the datasheet, there's probably a bit somewhere in the LPC controller that enables the smbus controller, you'll need to flip that first, if you haven't already.

as the last item. At least some progress is made. Besides the logging not working on cold boot, which it should at some point, I've now got something that works well enough to start proper debugging.
