2. remove pci_set_resource call
Update pci_bus_read_resources to read children's too.
Update pci_set_resource:
1. change logic for setting zero-size resources
A. Set range to [limit->limit-2^gran]
(Could have been any range with base > limit)
2. remove compute_allocate_resource calls
3. Change phase4_assign_resources ->phase4_set_resources

code boots and works on qemu and
alix1c. It represents a huge change and a huge improvement. There are a
few fixes left to do, which
will come once this is in.
This change started out easy: get the device IDs OUT of the the dts, and
into one place. We
decided the device IDs should be in the constructors ONLY. To make a
long story short, that just did
not work out, and it revealed a flaw in the design. The result?
- no more ids in the various dts files.
- the constructor struct is gone -- one less struct, nobody liked the
name anyway
- the device_operations struct now includes the device id.
- constructor property no longer used; use device_operations instead.
- lpc replaced with ioport
All the changes below stem from this "simple" change.
I am finding this new structure much easier to work with. I hope we're
done
on this for real, however!
TODO:
1. Change limitation in dtc that makes it hard to use hex in pci@
notation.
Now for the bad news. Sometime today, interrupts or io or something
stopped working between r596 and r602 -- but I did no commits at
that point. So something has gone wrong, but I don't think it's this
stuff.
I did try a build of HEAD, and it fails really, really badly. Much
more badly than this fails, so I think this commit is only going
to improve things. It does work fine on qemu, fails on alix1c,
so I suspect one of today's "clean up commits" broke something.

in dts. This gets rid of the ugly pcipath etc. properties.
So, instead of
somedevice {pcipath="1,0";};
We say pci@1,0{ etc. etc. };
As per my agreement I agree to document this in the design doc.
The alix1c compiles but is untested, and will probably need some work.
I will do these additional tasks on friday.

M include/device/path.h

one type of LPC. Clean up tabbing in parts of the file (cosmetic).

Change what used to be a BIOS_ERR (but is no longer) to a BIOS_NOTICE.
The change is that the device tree includes more than just PCI devices,
so finding a non-PCI device is no longer fatal; a notice is useful.

With these changes, the chipsetinit function now finds the southbridge

This success in turn means that the chipsetinit code is running for the

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.

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.
