 * (although the addresses stay the same so new S0 = old S1, new S1 = old S2).
 * We'll just use the 0-based numbering here for all platforms since it's the
 * way things will be named by the hardware team going forward, plus it's more
 * consistent with how most of the rest of our registers are named.
