You implement what the hardware you are modelling has, obviously.
This is why we have so many -- real hardware boards and SoCs
often use different devices to perform similar functions.
The software expects to see specific hardware when it runs
on a particular board model, so that is what we need to provide.

If you don't care what hardware you're using and just want
"some kind of Cortex-M board", then use one of the ones we
already have; you don't need to implement anything new.
The mps2-* and mps3-* boards are probably a good choice.
