Hi Russell,
Additionally, once all architectures convert to initialising their
serial ports via platform devices (which means include/asm-*/serial.h
becomes essentially empty) and we eliminate serial8250_console_init(),
the 8250 console code can start assuming that more of the uart_port
structure will be initialised.
At that point, we can start to think about using FIFOs for the
console.
Thank you for FIFO consideration.

I confirmed this assumption is OK in current code,
because seiral8250_ports[] is static variable.
We will release revised patch later,
please apply our patch until your serial driver
re-organization completes.
Thank you.
