Both old-IDE and libata should be able handle all controllers and
devices found using normal resource reservation methods.
This eliminates the awful, low-performing split-driver configuration
where old-IDE drove the PATA portion of a PCI device, in PIO-only mode,
and libata drove the SATA portion of the /same/ PCI device, in DMA mode.
Typically vendors would ship SATA hard drive / PATA optical
configuration, which would lend itself to slow (PIO-only) CD-ROM
performance.
For Intel users running in combined mode, it is now wholly dependent on
your driver choice (potentially link order, if you compile both drivers
in) whether old-IDE or libata will drive your hardware.
In either case, you will get full performance from both SATA and PATA
ports now, without having to pass a kernel command line parameter.

The following patch prevent this warning to be displayed again & again (eg:
nine times on my NForce2 motherboard) and thus improve signal to noise
ratio in logs.
The ATI quirk below probably needs a similar "fix" but I don't have
the hardware to test.
Btw arch/x86_64/kernel/early-quirks.c::nvidia_bugs() would probably need to
be synced (but I don't have an x86_64 NVidia motherboard to boot test it).
Still it shows the usefullity of the recent x86 merge thread.

__get_phys is only called from init.c as is prom_virt_to_phys(),
__get_iospace() is not called at all, and sun4u_get_pte() is largely
misnamed.
Privatize the implementation and helper functions of
sun4u_get_phys() to mm/init.c, and rename to
kvaddr_to_paddr().
The only used of this thing is flush_icache_range(), and thus
things can be considerably further simplified. For example,
we should only see module or PAGE_OFFSET kernel addresses here,
so we don't need the OBP firmware range handling at all.

Decrease the SECTION_SIZE_BITS --> MAX_PHYSADDR_BITS
range a little bit.
The cost of going to SPARSEMEM_STATIC becomes 8K of BSS space, and in
return we save a pointer dereferences on every page struct lookup.
Even better we hit the main kernel image for the base address which is
in a hugepage locked TLB entry.

This helps deal with the invisible bridge that sits between
the host controller and the top-most visisble PCI devices
on hypervisor systems.
For example, on T1000 the bus-range property says 2 --> 4
and so there is a PCI express bridge at bus 2, devfn 0, etc.
So if we don't force the dummy host controller to bus zero,
we'll try to create two devices with the same domain/bus/devfn
triplet.
Also, add some more log diagnostics to make debugging stuff like this
easyer.

The SIMBA APB bridge is strange, it is a PCI bridge but it lacks
some standard OF properties, in particular it lacks a 'ranges'
property.
What you have to do is read the IO and MEM range registers in
the APB bridge to determine the ranges handled by each bridge.
So fill in the bus resources by doing that.
Since we now handle this quirk in the generic PCI and OF device
probing layers, we can flat out eliminate all of that code from
the sabre pci controller driver.
In fact we can thus eliminate completely another quirk of the sabre
driver. It tried to make the two APB bridges look like PBMs but that
makes zero sense now (and it's questionable whether it ever made sense).
So now just use pbm_A and probe the whole PCI hierarchy using that as
the root.
This simplification allows many future cleanups to occur.
Also, I've found yet another quirk that needs to be worked around
while testing this. You can't use the 'class-code' OF firmware
property, especially for IDE controllers. We have to read the value
out of PCI config space or else we'll see the value the device was
showing before it was programmed into native mode.
I'm starting to think it might be wise to just read all of the values
out of PCI config space instead of using the OF properties. :-/
