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. -- Dan ** Sent via the linuxppc-embedded mail list.
