running configuring cycle across the host side of a 21554 non transparent bridge

[bhupinder sahran]

hi all
i am bhupender.
i am having a 21554 pci bridge between two processors.
on the local side of the bridge MPC8240(linux) is
sitting.
from the local side i want to run configuration cycle
of the host(primary) side of bridge.
i am using semaphore method given by intel
documentation.
i have enabled the configuration up bit also.
i am always getting 0xffffffff in my upstream config
data register.
can anybody tell me what could be the problem
thanx in advance
bye
bhupi
