David S. Miller 059833eb81 [SPARC64]: Range check bus number in SUN4V PCI controller driver. 
It has to be somewhere in the range from pbm->pci_first_busno to
pbm->pci_last_busno, inclusive.

David S. Miller 3833789bb2 [SPARC64]: PCI-SUN4V fixes. 
Clear top 8-bits of physical addresses in "ranges" property.
This gives the actual physical address.

Detect PBM-A vs. PBM-B by checking bit 0x40 of the devhandle.

David S. Miller 221b2fb818 [SPARC64]: Don't expect cfg space in PCI PBM ranges on SUN4V. 
PCI cfg space is accessed transparently through the Hypervisor and not
through direct cpu PIO operations.

David S. Miller bade562216 [SPARC64]: More SUN4V PCI controller work. 
Add assembler file for PCI hypervisor calls.
Setup basic skeleton of SUN4V PCI controller driver.

Add 32-bit devhandle to PBM struct, as this is needed for
hypervisor calls.

David S. Miller 8f6a93a196 [SPARC64]: Beginnings of SUN4V PCI controller support. 
Abstract out IOMMU operations so that we can have a different
set of calls on sun4v, which needs to do things through
hypervisor calls.
