New Revision: 295756
URL: https://svnweb.freebsd.org/changeset/base/295756

Log:
  Extract common code from PowerPC's ofw_pci
  
  Import portions of the PowerPC OF PCI implementation into
  new file "ofw_pci.c", common for other platforms. The files ofw_pci.c and
  ofw_pci.h from sys/powerpc/ofw no longer exist. All required declarations
  are moved to sys/dev/ofw/ofw_pci.h.
  
  This creates a new ofw_pci_write_ivar() function and modifies
  ofw_pci_nranges(), ofw_pci_read_ivar(), ofw_pci_route_interrupt() methods.
  Most functions contain existing ppc implementations in the majority
  unchanged. Now there is no need to have multiple identical copies
  of methods for various architectures.
