We do have a basic system test:
test-armv6m-undef: test-armv6m-undef.S
$(CC) -mcpu=cortex-m0 -mfloat-abi=soft \
-Wl,--build-id=none -x assembler-with-cpp \
$< -o $@ -nostdlib -static \
-T $(ARM_SRC)/$@.ld
run-test-armv6m-undef: QEMU_OPTS=-semihosting-config
enable=on,target=native,chardev=output -M microbit -kernel
ARM_TESTS+=test-armv6m-undef
But I guess this exercised more of the machine as micropython actually
comes up.

We could do more if we wanted - all the microbit specific stuff lives in
the microbit module:
