// @todo
// Per Dean, there's no access to the CFAM engines on the master processor, therefore,
// we *should not* allow access to them on any processor in any position
// from a FAPI standpoint.
// This means that get/put/modifyCfamRegister can't not be called on any of the processors.
// These functions, therefore, can only be called on the Centaur, which is not available
// at this time.
// When Centaur is supported:
// - Don't use i_target.front() (a processor) as a target. Set the target as one of the Centaurs.
// - Enable this block of code and test the cfam access functions on the Centaur.
