New Revision: 207287
URL: http://svn.freebsd.org/changeset/base/207287

Log:
  On sparc64 obtain the initiator ID to be used for SPI HBAs from the
  Open Firmware device tree in order to match what the PROM built-in
  driver uses. This is especially important when netbooting Fujitsu
  Siemens PRIMEPOWER250 as in that case the built-in driver isn't used
  and the port facts PortSCSIID defaults to 0, conflicting with the
  disk at the same address.
