I need to make a configuration patch for MIPS and PowerPC platforms that deals
with built-in RapidIO controllers available in some embedded SoCs.
For generic platforms with PCIe controllers 'tristate' changes similar to x86 are good enough.
I think it was mentioned in PATCH 0/7 that we will have a follow-up patch a bit later.
