Ok. Maybe you can send a patch to add those MSRs to msrtool Holger?
Have a look at http://stuge.se/mt.cs5536_pic_divil3.patch for one way
to note references in the source files.

I've had thoughts in that direction too. TODO mentions handling PCI
and port IO registers as well, ie. turn the tool into a more generic
register decoder. I kind of like that idea. On the other hand then it
will very clearly start competing with prettyprint that the Google
guys showed us. It looks like a somewhat fat implementation though,
which I'm not thrilled about. But they have a nifty user interface,
FUSE is a fun twist. I don't know.
We were discussing GeodeLink routing on IRC the other day, and how
it would be nice to e.g. create a bus graph by piecing together
values from various registers, but I'm not sure that kind of
complexity should go into msrtool. Or maybe it should? But a generic
user interface will be a bit tricky.. msrtool is already option
