I think Simons point was that Arm/Linux has a working full runtime. I guess
 bare raspberry pie would not and I guess it would be a rather large module
 or board or single board computer depending on the model.

WRT energy use. I use a low power run feature on the STM32L4 which means the
 system clock speed can change at any time. That seems to be incompatible
 with any runtime that I have seen except the minimal light-cortex-m4 one. I
 assume working with clocks is more scalable than working with runtimes but
 I do not know for sure.
