I was going to take a look around TIs site, I'd forgotten Pericom
makes bridges too, I'll read the data book.

I figured that was probably the case - and the reason the majority
of the embedded processors are sans-FPU. I didn't want to use a
TI DSP again, there's just no 'community spirit' like with Linux.

So, I'll take a look at the PowerQUICC that Wolfgang mentioned, and
see if I want to change to that processor, another look at the ColdFire
(I have an MCF5485 eval board), and a look at the bridge data sheets
and see where that leaves me.

Personally, I want to stay with the PowerPC, the developer mailing
list is great!

Thanks,
Dave
