PIO devices under uClinux

I got it working!!!

The problem was entirely mine and present in my code. I apologize for any time that was wasted.

Just for anyone else's benefit, the simplest method that worked for me was just to declare a pointer of type np_pio. I then used the variables within the structure to address the peripheral directly. It works great. I DID NOT have to remove DCACHE either, so the MSB of the address being set truly does bypass the cache.

The error in my code was the use of a "<" instead of a "<<" to perform a bit-shift operation. I have done this thousands of times, but it was a simple typo.

Thanks for your help.
