Assuming that you need Ethernet: if you can use the FEC for Ethernet, that it does not matter much; otherwise I'd recommend to use 2SMC + 2SCC or 1SMC + 3SCC so that you have at east one SCC left for Ethernet. > I need a console, but no hardware flow control (which would force the > use of SCC). Should be no problem. The kernel on our FTP server was tested with 6 serial ports on a MPC860, with HW flow controll on all SCC's. The only problem in such a configuration is that you have only 4 BRG's so two ports have to share the baudrate with another port.
