How do you know? :)

For a serial console you need a serial port, yes. Whether you can reuse,
e.g., the memory-mapped serial port or need to write your own device
depends on the hardware you're trying to match and that also determines
what dependencies you have - timer and PIC are likely.

Have you checked http://repo.or.cz/w/qemu/openrisc.git?

Andreas
