* 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

further. It is only tested with my Kconfig build dir fixes applied.
Not sure how pretty this is. All the mkdirs increase build time by 0.2s,
so it looks a lot more nasty than it actually is. If wishes, we can create the
whole directory structure below build in the "prepare" target. It's not faster,
but more limited to one place.
The next step could be to spread out *_LIB_OBJ to lib/Makefile. in which case
it is nice that you can just write object.o instead of $(obj)/object.o or
$(obj)/lib/object.o ...
The top level modules (initram, stage0, stage2, ..) are still in $(obj).
So are the northbridge and southbridge object files - These require some more
cleanup anyways, as they're defined in the mainboard Makefile.

* fix a whole lot of lar bugs (that never showed up in production yet)
* add proper option parsing to lar
* add verbose option
* add option to automatically pad lar archive to a certain size
* add proper file handling (specifying a directory will now pack all files
in that directory into the lar, instead of a 4k dummy file)
* catch lots of user errors, less implicit assumptions
* merge all header files into lib.h (except lar.h which is needed by other
programs using the lar format). lib.h is still very small.

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.

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

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.

Note that we have include/lib.h, and define all the functions in there,
instead of in lots of fiddly includes.

something that makes sense.

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.
