I would like to understand this one in detail to see why there
is cp15 in the build.
In ARMv7-M the system registers are memory mapped.
If I compile a Cortex-M based BSP with -O0, then I get:
BSP?
For example the atsamv BSP.
could you please have a look at this. Being able to build with -O0
is quite helpful during BSP development.
Is this important for 5.1.0?
It is not absolutely necessary, but I regularly had to fix this
locally. We have several ARMv7-M based BSPs. This was my first attempt
to address this issue:

We work no on another Cortex-M based BSP and building with -O0 would be
really nice.
