Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/sfr/ofcons

* 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/sfr/ofcons:
  Create drivers/of/platform.c
  Create linux/of_platorm.h
  [SPARC/64] Rename some functions like PowerPC
  Begin consolidation of of_device.h
  Begin to consolidate of_device.c
  Consolidate of_find_node_by routines
  Consolidate of_get_next_child
  Consolidate of_get_parent
  Consolidate of_find_property
  Consolidate of_device_is_compatible
  Start split out of common open firmware code
  Split out common parts of prom.h
