submodule updates (SLOF & dtc) 2017-03-03 This set of patches updates the SLOF and dtc submodules for qemu-2.9. The SLOF update could have gone in my ppc pull request earlier today, but I forgot it. It should be safe to apply in either order with that set though. The dtc (and libfdt) update brings us up to dtc 1.4.3 which includes some things that will be useful in future.
