            This option controls whether or not the Branch Target
            Buffer is enabled. The BTB is used for branch prediction
            and can have significant performance benefits. Control
            is provided because there is an errata for A-step 80200
            CPUS which will lead to problems with thumb branches
            if the BTB is on. Normal ARM programs are not affected
            by this errata."
