aa01c41f42 A bunch of small cosmetic improvement of the printk() calls (trivial).
Add "(LB) " to all log messages to differentiate them visually
from the rest of the boot messages. This is similar to what
Xen does when booting (it prefixes all log messages with "(XEN) ").

446979be46 This set of changes:
- makes sprintf work, in a re-entrant way
- gets rid of a lot of ugly debug stuff (thanks for the Kconfig log
  level stuff guys!)
- boots like a bat out of hell on qemu :-)

The changes are trivial, I am self-acking. 

To run this under qemu, I do this:

cp LinuxBIOSv3/build/linuxbios.rom bios.bin ;  qemu -nographic -L .
-kernel linux-2.6.15-bochs/vmlinux -hdc hda -hda hda | tee  out 2>&1

here is the output from a run. Note that cpu's still don't have a path
of any kind, and that show_all_devs is not working right. But we're
getting there. I think I'll next try to really boot a linux with a hard
drive, and see how it goes.

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.

ff7df4f7ad Add cross compilation support and simplify the far to complex serial
code (This goes hand in hand, as some parts of serial were hardcoded
to one architecture until now)

* include/uart8250.h: add TTYSx defines that are used in
  multiple places. formerly part of arch/x86/serial.c.
  Drop init_uart8250 (unused)
* lib/uart8250.c: drop arch/x86/config.h usage
  Drop init_uart8250 (unused)
* arch/powerpc/Kconfig, arch/x86/Kconfig: add CONFIG_ARCH to
  contain the directory name under LinuxBIOSv3/arch/
* arch/x86/console.c: drop some dead code. Drop hardcoded config.h values.
  use generic uart8250.h header
* arch/x86/cachemain.c: Drop hardcoded config.h values. Still use hardcoded
  ROM size for now. (To be changed later)
* arch/x86/config.h: dropped, no longer needed
* arch/x86/serial.c: factor out generically used defines to uart8250.h
* Makefile: use mainboard architecture instead of target architecture to choose
  include path.
  Read .xcompile if available (configure replacement).
  Create build.h with compile time and version.
* util/xcompile/xcompile: new file. Search for supported cross compilers
  linkers, assemblers (and potentially supported compiler flags etc)
  This is a very slick configure replacement.
* util/dtc/Makefile: fix Makefile for cross compilation

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.

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.

5274be0191 Add an emulation northbridge for the 440bx. The emulation is necessary
because not all emulators get the ram size registers right, or so we
hear. 

This northbridge is still incomplete. We are not just copying the v2
one, as we are trying to undo the various hacks that crept in over the
years, due to limitations in the v2 device model. Just look at the
i440bx in v2 and you can see what I mean. We are working to find a
better way to get the job done than those hacks. They are just too
confusing for people to follow. 

add an include for the northbridge makefile into the qemu Makefile. 
Re-order the includes in arch/x86/Makefile so we can pick up .o files
from other places. Add a STAGE2_CHIPSET_OBJ for objects defined in those
makefiles included in mainboard. 

Current issues: the enable_dev function for the i440bx is not getting
called. Enable_dev should be renamed to phase3_setup or something that
actually means something. The name as it is is totally useless.

7514f6507c This wraps up re-adding linuxbios table support in a limited form.
Remaining to be done: 
PIRQ table
MP table
ACPI table
relocate the GDT reload to a sensible place -- or figure out if we even
need to bother; we're back to execute in place and the GDT is in flash
rom ==> we can leave it until we boot the payload I think. 

At this point, however, we've got the basic bits to sensibly create
tables. 

This has been tested and works on bochs. 

It is working to a point, but still failing on qemu for reasons we don't
quite understand.

4282d12cdc Initial cleanup of the linuxbios tables code. Now it seems we need
resource .c functions -- sigh -- this will be next. 

fix types, fix some usage, but we do not yet generate pirqi, mptables,
or acpi. This will be next. 

This code will be called from phase6 in stage 2, and probably 
attached to a cpu. Or, it will be inline in the stage2.c code, since 
the need for tables is generic. 

I'm also going to move the cryptic usage of lgdt from here to stage 2,
phase 2, of the cpu code. The device model improvements are making it
easier to think about when things happen, we are finding. 

I'm going to get lunch and go see some of brussels. It's a miserable day
but ...

cd4625560e add tables support to LinuxBIOS.
We have merged the plethora of include files into one. A given linuxbios
target architecture must support all the functions described therein. 
All the structs etc. in include/tables.h are known to be
architecture-independent. 

We hope this new layout is easier to folow than the old one. 

Todo: Remove the LGDT code from tables writing (how did THAT get in
there ;-) and put it somewhere sane; add OFW table support. We are going
to need some nice OFW table code. 

Also, the license headers should be correct in this commit.

327a4432fe newelfboot.c. this elfboot is tremendously simplified so it can run out
of FLASH. Since it runs out of FLASH, we have removed the need for
bounce buffer support. that in turn rips out all kinds of stuff, so it
is now simpler. We're ripping out all the checksum stuff -- lar does
that. 

lar.c has some debug prints removed. 

elfboot.c has some mods, but elfboot.c is going away. 

cachemain.c has a few mods for using newelfboot. 

Makefile reflects these changes. 

Not tested, I'm going to bed though, so here you are.

08016c4ca8 Basic elfboot functionality is in now.
We're trying to avoid the bounce buffer mess, which is really complex, 
by running elfboot out of the boot block. This code includes a really 
dumb allocator in elfboot which may or may not work. It basically
allocates off the elfboot() stack. 

This builds, but elfboot is not tested. That's next.
