(Looks like our previous emails have crossed)

I can see the argument for renaming the FMT argument to avoid confusion 
with proper types, but introducing TARGET_FMT_plx seems a little 
excessive. I'm merely sticking with the existing OpenBIOS convention 
rather than attempting to change it within the scope of this patch :)

I really can't get too excited about this as I don't see what benefit it 
would have over a single commit to implement the type change in this case.
