[Qemu-devel] [PATCH 36/40] PPC: E500: Move PCI slot information into params

[Alexander Graf <agraf@suse.de>]

We have a params struct that allows us to expose differences between
e500 machine models. Include PCI slot information there, so we can have
different machines with different PCI slot topology.
