267ce7cbf7 This patch should serve as a porting help for other northbridges for the new resource allocator.
file-by-file changes:

dts:
	There are no bus devices, remove it.  Add the northbridge devices.
	Fix susbsytem_vendor and subsystem_device.

southbridge/intel/i82371eb/ide:
	Make the ide enabled by default.

northbridge/intel/i440bxemulation/i440bx.c:
	1. Split ops into domain and northbridge
		A. Domain should have bus ops, scan_bus, etc.
		B. Northbridge should have ops for its own registers.
			In this case it only needs read and set resources.

functions:
	i440bx_read_resources - set up the IO and VGA resources.  VGA is fixed.
	i440bx_ram_resources - this should be called after resource assignment.
	i440bx_set_resources - call pci_set_resources then i440bx_ram_resources.
	i440bx_domain_read_resources - Set up system-wide resources, and
		reserve space for the local APIC.  I put the IOAPIC here too,
		but it belongs somewhere in the southbridge.
	i440bx_domain_set_resources - Mark the domain-specific resources as
		stored (In a real device you'd probably need to set some
		registers here.)  Call phase4_set_resources for children.

southbridge/intel/i82371eb/i82371eb.c:
	1. Add ISA read and set resources to reserve legacy IO space.
		- Note that since it's subtractively decoded, it doesn't need
		to be stored anywhere.  It needs to be marked stored so
		pci_set_resource doesn't try to store it.

5e4770fc02 Prepare for per-device subsystem IDs.
Fix the bus location for Qemu IDE.

This patch only provides the needed infrastructure for per-device
subsystem IDs, it does not hook them up to the PCI core yet, so this
patch is a no-op.
By the way, the on_mainboard property is activating lots of completely
untested code paths in v3, so someone might want to audit them.

b1596f216b Rename mainboard_part_number to mainboard_name in various places. This
is the logical continuation of r416 which happened a year ago.

As an added bonus, we now have consistent naming again, making grepping
the source for dts properties possible.

Build tested on all targets. Patch attached for Gmail users.

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
Add LPC path type, replacing SUPERIO path type, since SUPERIO is only
one type of LPC. Clean up tabbing in parts of the file (cosmetic).

M    mainboard/emulation/qemu-x86/dts
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
Add ID info for the chip. 

M    northbridge/intel/i440bxemulation/i440bx.c
Change initialization so it is explicitly for the .ops struct member. 

M    util/dtc/flattree.c
Add support for the new path naming scheme. 
I'm in the middle of this commit so I'll fix the hard-coded lengths 
next commit. 
Also delete dead code between #if 0 and /* and //

M    util/x86emu/vm86.c
comment out unused variables. these may someday be use, not ready
to delete them yet. 

M    Makefile
Change -O2 to -g. We need debugging on LAR far more than we need performance.

This patch adds artec dbe61 support, removes all mainboard.c, and
 adds
 the code to dtc so that it takes these properties from the top level
 dts:
 /{
 .
 .
 .

      mainboard-vendor = "AMD";
      mainboard-part-number = "Norwich";
 }

 statictree.h will have:
 extern const char *mainboard_vendor, *mainboard_part_number;

 and statictree.c will have:
 const char *mainboard_vendor = "AMD";
 const char *mainboard_part_number = "Norwich";

 It is an error to NOT have the vendor and part number in the top
 level dts.

 thanks

 ron

Get rid of mainboard.c in all mainboard directories.
Modify dtc so that it creates declarations (in statictree.h) and
generates the char *
for mainboard name and part # (in statictree.c).

Failure to set up a mainboard-vendor
OR mainboard-part-number property in the mainboard dts will get a
helpful and descriptive error message (tested).
This may be a first for the linuxbios config
tools.

Add Georgi's patch for the bug in flattree.c; assign *cp = 0.

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

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.

b41e38e4a2 This is odd, but try again.
Comitting IP checksum code, and its usage in linuxbios table creation. 

Mods to the dts, so that the device ops for the domain are set to the
proper structure. This change is important. It gets rid of the obscure,
confusing use of the enable_dev function to pick the right ops for a
device. It makes the ops initilization very clear at the top level, in
the dts. This has been tested and works, linux boots on Bochs under
this version.

53283b1e36 fix a stupid bug in malloc.
add debug printks. 

make dtc put 'root' as the first_node, instead of making the last node
be the first node .... much happier in linuxbios. 

sprintf is broken ... dammit. I hope someone will fix it. I've got about
another week of full-time I can spend on this and then I go back to part
time. So I'm going to need some help soon.

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
