Hi, I tried using of_serial.c on a (PPC) MPC8241 based system, which has a "16650A" compatible double UART built into the SoC. Using of_serial.c causes the ports to be autoconfigured, and this fails. The loopback test fails, because the MSR register on 824[15] doesn't implement the UART_MSR_DCD bit. Question: what's better, teach 8250.c to handle UARTs without this bit, or set the UPF_SKIP_TEST bit in of_serial.c for these SOCs to skip the loopback test altogether? The latter is certainly easier and affects much fewer systems, so, I'd go for that.
