I'm thinking about taking the plunge and OCPfying 8xx so perhaps we
can get this thing organized.

I'd like to have a hierarhy of the peripherals like so:


                  ______- CPM -______  ___________  ___
                 /        /          \            \     \
                /        /            \            \     \
            Timers     SCC1..n _       SMC__      IDMA   DSP-f  etc.
                      /  |  \   \      |    \
                     /   |   \   \      \    \
                 UART  HDLC Enet QMC     UART Transp.
                                 /   \
                         HDLC0..63  Transp0..63

Of course with only one protocol active per SCC/SMC.

Is something like this supported with the OCP code, and if not
how could I get around in making it work?

IMO, we could share alot of the stuff between the CPM1/CPM2/CPM3...

Regards

Pantelis

P.S. I suck at ASCII art
