 * these are represented as a 2-element array where the first element
 * is the non-secure copy and the second is the secure copy.
 * When the CPU does not have implement the security extension then
 * only the first element is used.
 * This means that the copy for the current security state can be
 * accessed via env->registerfield[env->v7m.secure] (whether the security
 * extension is implemented or not).
