   > @brianwyld that's why I suggested it should be configured by either MCU or BSP. OS code can e.g. include some file from BSP where proper definitions can be expected. I did not look through the code to see what is the best way to do this now, perhaps we need to add something.
   
   So, I'm trying to find a place to set OS_IDLE_STACK_SIZE linked to the case where we want to ask the BSP to take actions pre/post entry to os_tick_idle() [to power off external peripherals for example]
   But this needs to be including a file from BSP as only the BSP knows what code its going to have to call (and hence what impact on the stack will be). 
   Is it legitimate to include <bsp_defs.h> from the BPSs in os.c after assert.h (so it can set OS_IDLE_STACK_SIZE to override the value in arch/common.h?)
