The cmdline is something that bootloaders typically allow to configure, while the other ATAGs are static and should be in the .dts file.Once the libfdt code is pulled into to manipulate the command line, it becomes trivial to parse the rest of the atags too, so this probably won't make much difference (unless work is done to preparse the devicetree and provide to the zimage wrapper a direct offset to the cmdline buffer in the dtb, but that gets hairy and I really don't want to go down that path).
OK, makes sense.

Adding a default command line to the .dts file instead of using CONFIG_CMDLINE_FORCE also works.But that requires carrying extra patches for something that should be user configured.. So not so nice for distros.Right, so this is only a stop-gap solution. I'll add this to the list of topics to discuss in the device tree session at Linaro at UDS next week.
Thanks Tony
