Bright Star Engineering offers an SA-1110 board with PCI host bridge. They
also had (but I don't see at the moment) a development kit which provided
a PCI backplane into which you could install standard PCI cards for
prototype development (AFAIK, most FireWire controllers are going to
be PCI based devices - Card Bus by definition is PCI). Have a look here:
http://www.brightstareng.com/arm/nanoeng.htm
I'm not aware of other SA-1110 designs which include a PCI host bridge.
Again, to my knowledge, there is no standard PCI host bridge available
for the SA-1110. The bridge used in the BSE nanoEngine is a custom
CPLD based device.
Also, have you checked other vendors' device offerings, Sharp, Samsung,
etc.,.
IIRC, the TI OMAPI DSP+ARM device may include a firewire controller?
But then you'll probably have to wait for silicon...
