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
