Writing Pin-muxing registers in an am3359.

[Bob Stewart]

Christian,

Thanks for your thoughtful reply. I've been looking at  an extension to IO 
memory services in the kernel to access a restricted region,  and adding 
parametric enabling of it is a good idea. My thinking was that setting the 
pin-mux registers should be done a driver separate from the gpio driver and 
that driver should read a config file to get the settings,  then exit. All 
the use cases I'm dealing with require an initial set up then the 
applications execute using those settings without changing them.

I'm currently using foc but I intend to go the base-hw route shortly. If 
time permits,  I'll look into using the handle_slow_trap Thread method  as 
learning exercise.

Again, thanks for the reply.
Bob
