+ * A_TARGET_ACCESS_LIKELY will not wait for the target to wake up before

+ * target access, A_TARGET_ACCESS_LIKELY hints are optional.
+ *
+ * To ignore "LIKELY" hints, set CONFIG_TARGET_ACCESS_LIKELY to 0
+ * (slightly worse performance, less power)
+ *
+ * To use "LIKELY" hints, set CONFIG_TARGET_ACCESS_LIKELY to 1
+ * (slightly better performance, more power)

+ * note: if a bus doesn't use hif_target_sleep_state_adjust, this will have
+ * no impact.
