At Shakti they are working on that; there are quite a lot experimentations with embedded boards in the (small) community of people who work on the core. They might provide ARM compiles (they already work) so it should work on quite a range of devices; however you do need somewhat more memory than for instance I am used to work with (MCU's with 23 kb usable memory); I think it needs at least a few 100kb to do anything and (probably) a few meg to do actual work with it. It'll improve.
