724 * This test will find single-bit

727 * address and size of the region are
728 * selected by the caller.

732 * guarantee single address bit changes.
733 * For example, to test a 64-Kbyte
734 * region, select a base address on a
735 * 64-Kbyte boundary. Also, select the
736 * region size as a power-of-two if at
