I have a custom board based on MPC8272 and I don't succeed to enable SMC serial port. I'm running Linux 2.6.12.3 with CPM serial drivers from 2.6.13.2. When I configure the kernel to use one or two SCCs, with or without serial console everything works fine. But if I configure the kernel to support SMC serial port, I see nothing at the SMC port. I've noticed that SMC1 pins are configured at port D (as in MPC8260), but MPC8272 has the SMC1 on the port C. I've changed the pins assignment to use the port C pins, but it didn't help. When I enable support for serial console on SCC/SMC port, the system hangs when the SMC is enabled. When I don't enable support for serial console on SCC/SMC port, the system boots OK, but there's nothing on the SMC port.
