Subject: [SBUS]: Start cleaning up generic sbus support layer.

In particular, move the IRQ probing out to sparc32/sparc64
arch specific code where it belongs.

Subject: [SPARC64]: Import OBP device tree into kernel data structures.

The basic framework is based on the PowerPC OF code.

This code even tries to get the device addressing components
correct in the full path names.

Subject: [SPARC64]: Fix for Niagara memory corruption.

On some sun4v systems, after netboot the ethernet controller and it's
DMA mappings can be left active.  The net result is that the kernel
can end up using memory the ethernet controller will continue to DMA
into, resulting in corruption.

To deal with this, we are more careful about importing IOMMU
translations which OBP has left in the IO-TLB.  If the mapping maps
into an area the firmware claimed was free and available memory for
the kernel to use, we demap instead of import that IOMMU entry.

This is going to cause the network chip to take a PCI master abort on
the next DMA it attempts, if it has been left going like this.  All
tests show that this is handled properly by the PCI layer and the e1000
drivers.

Subject: [SPARC64]: Add of_device layer and make ebus/isa use it.

Sparcspkr and power drivers are converted, to make sure it works.
Eventually the SBUS device layer will use this as a sub-class.

I really cannot cut loose on that bit until sparc32 is given the
same infrastructure.
