Well, the cmdline I added is the switch of early console enable, which I should enable CONFIG_SERIAL_8250_CONSOLE in kernel config first.

For the moment, I don't have such a cute hardware tool which can support source code debug like BDI2000. To be frank, I haven't used a hardware tool to debug kernel.
