PPC440EPx GPIO control help

Hi Dell,

If you do decide to look at kernel drivers, Jeff has sent you
code, and I also have a tutorial with example code you are
welcome to look at:

Feel free to ask questions. I recall writing some test driver
code for the 440EP Yosemite board too. I'm just not sure where
I put it ...  :)

Cheers,
Dave
