The SMP configuration will run with:
CONFIG_SMP_NCPUS=1
In this case there is, of course, no muli-CPU processing, but this does
verify the correctness of some the basic SMP logic.
The NSH configuration can also be forced to run SMP, but suffers from
the same quirky behavior. I can be made reliable if you modify
arch/sim/src/up_idle.c so that the IDLE loop only runs for CPU0.
