>>This is defined when the board is produced
That sounds like complete nonsense, can you provide an actual cite?
Do you mean what ARM IP ST chose to include in their Cortex-M0 chip level implementation?

As far as I'm aware ST chose to have the multiplier, systick and debug functionality. "Single-cycle 32-bit hardware multiplier"
Should be easy enough to measure ones' self if there is any doubt.
