I point out that device trees are becoming standard in the Linux kernel, and
being spread from powerpc and sparc to arm, mips, and so on. I attented a
BOF about them at OLS, and there's even a mailing list for them now:
https://ozlabs.org/mailman/listinfo/devicetree-discuss
This means the Linux kernel already has data files which describe boards on
architectures that don't have big defacto standard hardware layouts already
implemented in C, and lots of 'em are yanking the C implementation in favor
of using the device tree parser.
Teaching qemu to parse a device tree means you get a ton of free board layouts
from the linux kernel. (It also simplifies "-kernel" since lots of platforms
need the flattened device tree passed in from the firmware...)
Somewhat out-of-date documentation is available here:
http://kernel.org/doc/Documentation/powerpc/booting-without-of.txt
You could ping the above list to see if there's something more recent...
