31a9e22fa4 A lot of the v3 header files require other header files to be #included
before they can be #included. That is completely counter-intuitive. Add 
necessary #includes to the header files themselves.

Fix a few cases where nonexisting files were #included.

Compile tested on Qemu and Alix1C.

f7ad196c0a This started out as a trivial change and turned into a big change. This
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.

4a6a5313bf The real change here is that paths can now be part of the node label
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).

Modify this dts for the new path naming scheme.

M    device/pci_device.c
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. 

M    device/device_util.c
Add string creation for PCI_BUS nad LPC.

M    northbridge/intel/i440bxemulation/dts

0044d53a10 This set of changes creates irq tables for alix1c and adds the functions
from v2 to install them. Linux boots fine and all interrupts
seem to work correctly -- the network comes up, USB hot plug works, 
I can mount the USB disk, etc. 

To enable pirq tables for a given mainboard, simply add the 
select PIRQ_TABLE (see below) to the Kconfig for that board. 

Again, this code builds and boots linux on the alix1c.

I think, with this change, we are very close to moving ALL LX boards to 
v3 and deprecating v2. The major remaining fix is to add an empty LAR 
entry to fill empty space in LAR and speed up the LAR file search 
process.

7c1623aec3 include/device/device.h:
Change the ID constants so they are more useful for debugging. 
Instead of simple 1,2,3 they now are a 4-byte value which can be more
useful when looking at memory with a debugger. Lots of variables can be 
'1', but fewer variables will match to 'PCID'. 

include/device/pci.h: 
Include pci_ids.h in pci.h

device/device.c: remove silly comment. Change memcpy to struct assign, this makes it possible 
for the C compiler to do type checking. Add assign for the dev->id. 

flattree.c: Support the use of 'domainid' and 'pciid' in the per-chip dts. These IDs will be assigned
to the static tree device struct. In conjunction with the earlier patch, this change removes the need
for users to assign the ops struct member in the dts by hand, as it is done in the qemu port today. 
The ops struct member will automatically be assigned by the dev_init function, which is run 
in stage2 before any actual device code is run. (This change to dev_init was in the previous patch). 
Added two comments that document what is going on.

7e806b90e6 This change is for tidying up some unfinished business in the device code.
I just uncovered this problem while trying to get the lx going. 

The symptom was that the northbridge ops were never getting run, 
in particular the phase 2 ops for the geodelx were not running. The 
reason was that the ops struct member for the device was not set. 

How is the ops struct member set? 
Currently, the ops vector for a static device (i.e. a device created from the 
dts) has to be set by hand, as in mainboard/emulation/qemu-x86/dts:
	domain0 {
		/config/("northbridge/intel/i440bxemulation");
		ops = "i440bxemulation_pcidomainops";

This requirement is ridiculous (it's my fault). If we know the part, 
and have the dts, we should not have to explicitly name the ops. In fact the
constructors array, defined at the end of the various device files, makes 
searching for an ops struct for a dynamic device automatic. We should 
support this automatic behavior for static devices too. 

Given the function find_constructor
in device/device.c, why don't we just use that? The problem is that we did 
not set up the device struct to include a device id, just a device path, and
find_constructor requires a device_id -- which makes sense, I hope, 
as the path is its pci path (e.g. 0:1.0) and the constructors are defined by the 
device id (i.e. it is the same constructor for a given part, no matter how many
of the part we have). 

So, as a start to fixing this limitation (this is going to take several patches), 
I've done the following:
1. add a struct device_id to the device struct. 
2. extended the dev_init code in device/device.c -- this is the first function
    called from lib/stage2.c -- to find a constructor for the dev->id and, if
    found, set dev->ops to it. 

Result: for static devices with the id set, the ops pointer will be set 
automatically. Coreboot builds fine with this change. 

The next change will be to add dtc commands to set ids. 
Currently, we have commands like pcipath, pcidomain, etc.; 
the new commands will look like pciid, domainid, etc. Once we have these
commands, we will have made it possible to set ops automatically. We 
can just set the ids in the device dts file, and users will never have to 
see any of this complication. 

The final change will be a bit more complicated. Right now, if you look in, 
e.g., northbridge/amd/geodelx/dts, you'll see that we have one dts, but 
the northbridge plays three roles. We can't easily contain those three 
roles in one dts (I am open to suggestions showing I am wrong). 
I am going to propose that we have more than one dts file
in a directory, so instead of 
northbridge/amd/geodelx/dts 
we would have
northbridge/amd/geodelx/dtsdomain
northbridge/amd/geodelx/dtsapic
northbridge/amd/geodelx/dtspci
so that we could set the variables for each of these individual components. 

There is no need to split geodelx.c into three .c files, however. 

Finally, I will be removing the archaic vendor and device unsigned's from
the device struct in future, but as I say, I am trying to stage these changes
to keep them understandable.

it seems) code. As we stopped using device_t long ago, these should
be removed, too.

For reference, device_t previously was:

  typedef struct device * device_t;

* include cleanup. We don't provide stdint.h, so use arch/types.h
  instead.
* drop some unused variables
* fix comment style in some headers to match the template

0528863e20 This patch reshapes northbridge and southbridge inclusion. It selects
southbridge drivers in Kconfig.

* It includes initial superio code as well, but there is at least one
  error in the pnp_device.c/superio scenario left

* Fixed biosemu.c, vm86.c, pnp_device.c (sort of)

* Enable vm86 instead of x86emu per default for vga init for now. This
  makes VGA in qemu work. There might be a bug in x86emu or the compiler
  I am using. (gcc version 4.1.2 20070115 (prerelease) (SUSE Linux))

* Import isa-dma.c, keyboard.c and i8259.c from v2 /pc80, which was taken
  from LinuxBIOSv1 released from LANL under release LA-CC Number 00-34
  and using parts from the Linux kernel.

This patch makes vga and keyboard work in qemu. Yippie

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.

(e81e557a8f1e22fab1b1bdc649ac0d24017ddce2).

our own short list for LinuxBIOS (we don't need that many entries).

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.
