Setting up a configuration ROM

Hi,

We're a hardware vendor, and we're building a card with a PowerPC running
Linux and a FireWire chip. We're using TI's TSB82AA2. How do we go about
programming the EEPROM that's connected to the chip? Is there any utility to
do it?

How do we go about finding out WHAT we should actually put there? Is there
any ROM image to start with?

And finally, can the current driver possibly work with this chip without the
EEPROM at all? (The chip can be configured that way.)

Below are the kernel messages that I get right now when I boot the kernel
and then connect a FireWire device. Evidently, it is not working. Maybe from
a glance you guys will be able to give some good advice. I'm working with
kernel 2.6.9 and the latest ieee1394 sources from SVN.

Thanks!
