sprintf is broken ... dammit. I hope someone will fix it. I've got about

other fixups, and also, make the dts conform to the needs of the device
tree. So we have a domain0 and a device (0,0) that is the north.
Mostly things are working, but we're STILL not getting any memory in the
LB tables from the north. The device tree is a bitch.

Change dts compiler to emit a new struct member, dtsname, for devices,
so we can get actual useful names for things.
Several mods and printks added.
printk(BIOS_SPEW
gives no output for reasons I don't understand.
Next in line is bringing back v2 support for pci, but not doing it the
way v2 does it.
note the cpus() printk above. cpus don't have a valid path yet.
We still need to work out the dts syntax for systems with multiple links

Also added comments.
A big change is in the dts. In OFW trees, the hierarchy seems to be:
/root/cpu/northbridge
south
other pci
note that the north is in the hierarchy under the south. This hierarchy
makes no sense on systems with a shared frontside bus, or at least I
don't see how it can. In those systems, it's easier to think about
the CPUs AND northbridges as children of the front side bus.
in LinuxBIOS, it has always been this:
/root/cpu/whatever
/root/northbridge/
south
other pci
There have been many discussions over how it ought to be, for 8 years
now, and we've always come back to how LB does it. So I have changed the
dts for qemu for now to match LB's way of doing things. Note that the
new system is flexible enough that, on K8, we CAN do things as above:
/cpu@0/amd8knorthbridge/etc.
/cpu@1/amd8knorthbridge/etc.
But on qemu, for now, the root is the mainboard, and the CPU and
northbridge are siblings.
I've added some informational printks, cleaned up pci_ops, and done
other things so that it builds and all seems to work -- until it hangs
hard in enumeration in i440bx ...

renamed the phase3 etc. to stuff like phase3_scan, so you can get a
rought idea what it is. The names mean more.
adding pci_device and, at the same time, showing how we can get rid of
the really ugly stuff that crept in. note you can specify ops in the
dts, which avoids the need for hideous stuff like this:
static void enable_dev(struct device *dev)
{
/* Set the operations if it is a special bus type */
if (dev->path.type == DEVICE_PATH_PCI_DOMAIN) {
dev->ops = &pci_domain_ops;
pci_set_method(dev);
}
else if (dev->path.type == DEVICE_PATH_APIC_CLUSTER) {
dev->ops = &cpu_bus_ops;
}
}
So that foolishness is gone.
added delay functions.
Note that we have include/lib.h, and define all the functions in there,
instead of in lots of fiddly includes.
Brought back the enable op, once I understood it; renamed it to
something that makes sense.
I'll be on a plane soon, will continue to work, but at least you can see
what's going on here.

because not all emulators get the ram size registers right, or so we
hear.
This northbridge is still incomplete. We are not just copying the v2
one, as we are trying to undo the various hacks that crept in over the
years, due to limitations in the v2 device model. Just look at the
i440bx in v2 and you can see what I mean. We are working to find a
better way to get the job done than those hacks. They are just too
confusing for people to follow.
add an include for the northbridge makefile into the qemu Makefile.
Re-order the includes in arch/x86/Makefile so we can pick up .o files
from other places. Add a STAGE2_CHIPSET_OBJ for objects defined in those
makefiles included in mainboard.
Current issues: the enable_dev function for the i440bx is not getting
called. Enable_dev should be renamed to phase3_setup or something that
actually means something. The name as it is is totally useless.
