Ummm, I'm confused.  The existing PowerPC OpenPIC works just fine with
the 8240/8245/MPC107 EPICs, at least on the Sandpoint.  I can't believe
there would be much of anything needed for a custom board.  I have some
Sandpoint X3 patches that enables the serial mode control lines as well.
I think there could be a few minor improvements, but it is certainly
functional.  All you should need are the interrupt senses table for
the OpenPIC initialization and the proper routing table for the PCI
setup.
