Then, the setup scripts tool should include that support and should have
support for auto.c too.

I agree. But maybe we find a nicer way of describing this.

Are these "hard coded" in hardware? 
The motherboard configuration should then probably contain a busnumber
value for each ht bridge that implements a pci bus

southbridge amd/amd8131 "amd8131"
        register "bus0" = "5"
end

southbridge amd/amd8151 "amd8151"
        register "bus0" = "3"
end

Or should this be handled distinct from the bridges with 
options like
option BUS1=99
option BUS2=5
?

currently the code that is generated (static.c) consists all of global
structs that are not directly usable with romcc code.
looking at the needs of auto.c it might be worth it adding a new
writeromccstructs definition that dumps into the right files and is only
called "on architectures that have romcc support" ;)

When i.e. generating hypertransport routing tables it would be nice to
have those directly generated in config.g. but then again, this adds up
a lot of cpu dependent magic to the config tool. What about having part 
specific configuration output in src/<type>/<vendor>/<id>/config.py i.e. 
have the opteron northbridge specific code that creates ht tables and 
writes auto.c's mem_controller struct in 
src/northbridge/amd/amdk8/Config.py. 
That would keep the configuration utility reasonably small and enhancable
while have the actual config file creator for each of the components at the 
same place as the other code parts belonging to that component.
