=A0I'm attempting to get SPI to work on my embedded design
=A0that is based on the mpc8313erbd reference board wiht a
=A02.6.27 kernel.

Are you able to use a more recent kernel?  A lot of work has gone into
SPI drivers in the last 5 releases.

=A0I cannot open the SPI device.
=A0Tracing through the kernel code, it looks like the device is
=A0not being found in the DTB file. =A0However there is a
=A0SPI node in there already described. =A0Our boards is a
SPI master, and the device we will attach is a SPI
=A0slave. =A0Could someone elaborate on what is needed in
=A0the DTS file to have our SPI driver work and respond to an
=A0open() call?

Look in Documentation/powerpc/dts-bindings/spi-bus.txt.  However, the
2.6.27 kernel may not have support for that binding on the mpc8313 SPI
bus driver (I'm not sure though, I haven't looked).
