I assume that you are speaking from the perspective of an
embedded CPU on the secondary side of the 21554.  We use that
configuration, and it is somewhat problematic.

Probably the best way is to watch the primary-side BAR
registers to become programmed with some value.  You will
still have to be careful about race conditions with regard
to other PCI devices, since you can't be sure in what
order they will be programmed.  Good luck..
