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.

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.

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 ...

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.

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.

add memcmp. Crude implementation, but it really does not matter.

accordance to the newboot document:
* reset vector (16 bytes)
* vpd (240bytes)
* boot block (8k - 256b)
* lar archive (256-8 k)
The boot block is kind of simple, still. It enables pmode, car, and
starts looking for an initram module in the lar archive.
Note: This doesnt do much at the moment,
as gas seems to produce buggy code in init.S.
Take this as a suggestion of how it might work and please provide
patches fixing it and bringing it into shape.
