The Cortex-M3/M4/M7 cores were designed as a replacement for the earlier ARM7TDMI and ARM9TDMI microarchitectures used in older microcontrollers. At the moment, Linux can run these cores either when they are integrated into a larger SoC, or as standalone microcontrollers. While there was a lot of development work going into Cortex-M support from 2011 to 2016, this largely stopped when it became clear that Zephyr and other RTOS had taken over that market. To date, the only Cortex-M based based microcontroller boards supported upstream are reference implementations. Schedule these for removal after the next LTS kernel, so if any users remain that want to update their kernels, they can stay on that version for a few years before having to maintain the platform support out of tree.
