FWIW, at the last OLS there was interest expressed by at least one
ARM-based platform and I'm working on a set of patches to add the device
tree for MIPS. It's going very slowly and is dependent on a patchset to
add support for our platform, so it will take a while to make it
available. The important point, though, is that device tree is the only
thing approaching a standard on any non-x86-based platform for passing
structured information from the bootloader to the kernel. The command
line is just not sufficient for this.
