Help text

Enable this option to test S32C1I instruction behavior at boot. Correct operation of this instruction requires some cooperation from hardware external to the processor (such as bus bridge, bus fabric, or memory controller). It is easy to make wrong hardware configuration, this test should catch it early.

Say 'N' on stable hardware.
