  Log:
  Add function OF_decode_addr(). This function obtains the physical
  address of the device identified by its phandle_t by traversing OFW's
  device tree. The space and address returned by this function can
  subsequently be passed to sparc64_fake_bustag() to construct a valid
  tag and handle for use by the newbus I/O functions.
  
  Use of this function is expected to be limited to pre-newbus access to
  devices, such as consoles and keyboards.
