3aaa72165e Drop the bogus license header I added to include/device/pci_ids.h.
Merely document that the file is based on the pci_ids.h file
from the Linux kernel (trivial).

We assume all code from Linux to be licensed under the terms of the
GPLv2, if no explicit license header says something else.

6869f4a129 new device model from Ron
This tree shows the new model. It demonstrates the constructor array
in use, for devices that are and are not specified in the dts. It
introduces a new generic structure, device_id, analogous to
device_path, which can describe all the types of device IDs we have.
It shows a way to set up arrays of structs, in the dts, for the
constructors, so we avoid ldscript hacks.

59365cfb45 Update pci_ids.h to the latest version from the Linux kernel
(e81e557a8f1e22fab1b1bdc649ac0d24017ddce2).

We stripped all PCI vendor IDs and device IDs, as we will maintain
our own short list for LinuxBIOS (we don't need that many entries).

Phase 2: done
Phase 3: Enumerating buses...
qemu-x86 enable_dev done
dev_phase3_scan: scanning Root Device
scan_static_bus for root(Root Device)
cpus: Unknown device path type: 0
cpus() enabled

i440bxemulation_enable_dev: DONE
northbridge_intel_i440bxemulation() enabled
northbridge_intel_i440bxemulation() scanning...
dev_phase3_scan: scanning 
pci_scan_bus start
PCI: pci_scan_bus for bus 00
PCI: scan devfn 0x0 to 0xff
PCI: devfn 0x0
PCI: pci_scan_bus pci_scan_get_dev returns dev <NULL>

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
(opteron)

7513bfdb03 Lots of changes here, build broken, but people need to see this.
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.
