For e500 our approach to supporting dynamically spawned sysbus devices is to create a simple bus from the guest's point of view within which we map those devices dynamically. We allocate memory regions always within the "platform" hole in address space and map IRQs to predetermined IRQ lines that are reserved for platform device usage. This maps really nicely into device tree logic, so we can just tell the guest about our virtual simple bus in device tree as well. Signed-off-by: Alexander Graf <agraf@suse.de>
