- * The primary factor in making this decision is the cost of disabling

- * body of the loop. On some CPUs, the flash is more expensive than
- * one iteration of the loop body. In this case, it might be desirable
- * to unroll the loop. It is important to note that on some CPUs, this
- * code is the longest interrupt disable period in RTEMS. So it is
- * necessary to strike a balance when setting this parameter.

- * Port Specific Information:
- *
- * The v850 is a RISC CPU which typically has enough memory to justify
- * the unrolling of this method.
