649c9f99ff Console:
(1)we now compile in all printks, which is good: we can print any message provided we can change
the console log level at any time. 
(2) The console log level is compiled in and unchangeable, which is bad, as it defeats the purpose of (1).

Add a BIOS_ALWAYS log level. Make console log level a variable. Make functions that set it and get it
visible everywhere. Always print out the version message; this is really *not* noise!

PCI: Simplify pci functions so that they can be used in stage1 or anywhere for that matter. Add
a find function which is needed for many stage1 functions. Note that we copy but also clean up
the libpayload stuff just a bit. 

Get rid of config space type 2. If there was ever a platform that used it, I don't know what it was, 
and the presence is a needless distraction. 

tested and working on DBE62 (which means the console and the pci functions work :-).

There is a remaining problem with dumplxmsrs which nobody understands. It prints out garbage if we use the 
%s for the msr names. 

Formatting is an issue; if somebody wants to fix formatting they can assume I will ack it. Sorry, 
my emacs has gone just nuts.

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.

Index: include/tables.h
Add prototype, conditioned on CONFIG_PIRQ_TABLE

Index: util/x86emu/vm86.c
Comment out 'debug trap' code that scribbles vectors at 0x4000. 
I don't know why this is here, but I'd like to leave it #if'ed out --
somebody, at some point, thought we needed it. To reenable, we will need
to move stage2 code or these magic vectors. 

Index: arch/x86/Makefile
Add support for conditional compilation of pirq support code. 

Index: arch/x86/pirq_routing.c
Add this file from v2.

Add call to write_pirq_routing_table (controlled by #ifdef

Index: include/arch/x86/pirq_routing.h
Add include file from v2.
Remove all the SLOTCOUNT nonsense. This hack was only needed
for a very early version of gcc 3.x, where they screwed up the 
creation of struct members that used the [] syntax for variable-length
array at the end of the struct. 

Index: include/device/pci.h
Add prototype

6220b632e7 Now version 3: LinuxBIOS -> coreboot rename.
- I left LB_TAG_ intact because they are used by the payloads
- file renames are still missing. see next commit
- some lb_ renames might be missing. feel free to provide patches.

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.

464ef4613d Use the same naming convention and placement for "include guards" in
all header files.

This closes #40, as I think we don't need to invest time to fix this in
LinuxBIOSv2, but only in LinuxBIOSv3.

71ccb36afc Massive file rename and moving orgy:
- Everything in include/cpu/generic/x86/arch/* goes into
   include/arch/x86 now.

 - include/cpu/generic/x86/div64.h moves into include/arch/x86, too.

 - The former include/cpu/generic/x86/arch/elf.h moved to
   include/arch/x86/archelf.h, as elf.h already exists in include/
   and we must prevent a name clash.

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.
