Playing with device trees under qemu?
Google is being unhelpful here. If I want to:
A) play around with the recent device tree support patches for the kernel
B) boot them under QEMU
Where do I go? The closest thing to a device trees website google finds is http://elinux.org/Device_Trees which doesn't mention qemu at all. There was a CELF proposal last year to add device tree support to qemu, which is inexplicably attributed to me:
http://elinux.org/CELF_Project_Proposal/Add_Device_Tree_emulation_support_to_QEMU
And google also found http://www.linux-kvm.org/wiki/images/f/fe/2010-forum-armbru-qdev.pdf
and a kvm (not qemu) status page http://www.linux-kvm.org/page/Qdev_status
but none of them are the "go here, download this, do that" variety...
Any suggestions, or is it not ripe enough to play with yet?

This is a good starting point, if a bit old. Things have moved on a bit since then and I should really write up the QEMU configuration that I'm currently using.
