About device trees, does the simulator need an explicitly provided device tree (in a way we currently provide the kernel image and ramdisk) or is the dt table built into the image? >>> >>> I'll be pushing a tree onto git.linaro.org soon with that stuff. >> >> >> Why don't you push the changes to the ARM LT and let them manage pushing the >> tree out.
