hi all
i have ported linux on my MPC8240 processor.
but as i am not having bios kind of stuff so kernek
should initialise all the peripherals sitting on the
pci bus.
i have intigrated the code, but code for mapping the
pci-pci bridge is not with me.
so i cam not see the device which are sitting on bus
after the bridge.
can anybody tell me where i can get this code.
thanks in advance
with king regards

I'm not sure I really understood everything you're trying to say but you can
start looking in mpc10x_common.c for some mpc105/106//107/8240 bridge init
code. You can look at the sandpoint port for how to use it. This code should
do most if not all of what you need to do.

I guess I should add that if you really mean setting up a PCI-PCI bridge (and not
the host bridge), try using the pci_auto stuff.
