Pete,


Please use the redwood5_config to start with( make redwood5_config).
The stb04xxx does not have a ocp ethernet.  The gpio driver will not
work on any stbxxxx processors since most of the other devices such as
video, sound and other drivers you get from IBM use many gpio pins so
having a generic gpio driver make no sense.  If you want to use the gpio
driver then you will need to update some of the ibmstb4.x files and the
driver.
