RFC QEMU patches to generate FDT from qdevs

Hi everyone,

This is an experimental set of patches for populating the flattened device tree (fdt) data from the actual set of qdevs in the platform. I'm not expecting this to get merged anytime soon, but I wanted to get it out there to solicit comments. My target for this is testing device tree support on ARM.

The approach is by no means final, and there are still a number of details to work out, but I've got it working well with the versatile platform and I've got the kernel using fdt data to bind against the smc91x device driver. I'll be posting my associated kernel patches real-soon-now.

This series is based on Jeremy Kerr's device tree branch found here:

git://kernel.ubuntu.com/jk/dt/qemu.git

Cheers,
g.
