There's two serial drivers, the polled one used by diagnostic I/O, and the
interrupt driven one used with eCos apps. It looks like you want the former
since that's what RedBoot uses.

You'll need anon cvs: http://sources.redhat.com/ecos/anoncvs.html
Then the file is hal_diag.c

Yes. If you are wanting interrupt driven operation with eCos it's a
separate driver even, under devs/serial/arm/iq80310
