            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."
