601 * address and checking for aliasing.
602 * This test will find single-bit

609 * address should have enough LSB 0's to
610 * guarantee single address bit changes.
611 * For example, to test a 64-Kbyte
612 * region, select a base address on a
613 * 64-Kbyte boundary. Also, select the
614 * region size as a power-of-two if at
