I've just pushed out changes implementing a new device API.

This is based on my previous RFC[1], but with a few changes. The main one
being increased used of proxies/wrappers to implement common bus
functionality. For example there are frameworks for PCI, "ISA"[1] and I2C
devices all built on top of a common core.

I think we should also have a generic BusState with a name and a list of devices attached (maybe more). Then have "BusState *bus" instead of "void *bus". Then you can actually walk the device tree in common code, for example have a "info devtree" monitor command printing all devices of the machine.

cheers,
