Hi all,

I have one fundamental question regarding the
configuration of pci to pci bridges with cpci
backplane. 

The proposed project configuration looks similar to
this.

1.	cpci back plane
2.	Three Force computers cpci680 cards (that have a
pci local bus and a pci to pci sentinel bridge)
sitting on this cpci backplane. One of the cpci cards
is used in system  slot and the remaining two cards
are used in peripheral slots.
3. vxworks OS

In this configuration how do we go about setting the
bridge configuration and memory mapping ? 

1. I understand the usage of the standard bsp routines
like frcpcibusstructinit(). But I am not clear as to
how we can map/modify the pci bus address space to the
cards/devices in the entire configuration and
interrupt management issues here. 

Any leads/tutorial links would be greatly appreciated.

Thanx and best regards,
rajendra.
