Perhaps other things to consider (I'm not entirely sure if these apply, but
maybe worth investigating?)

The ROS project has a meta layer:
https://layers.openembedded.org/layerindex/branch/master/layer/meta-ros/

If your CortexM board has enough RAM (e.g. http://www.emcraft.com/) you can
run (a version of) Linux (uClinux) right on your CortexM target:
https://github.com/EmcraftSystems/linux-emcraft

The Emcraft website appears to provide Linux support for NXP-based CortexM
boards too: http://www.emcraft.com/products/456
