654 * Description: Test the address bus wiring in a

658 * This test will find single-bit

661 * address and size of the region are
662 * selected by the caller.
664 * Notes: For best results, the selected base
665 * address should have enough LSB 0's to
666 * guarantee single address bit changes.
667 * For example, to test a 64-Kbyte
668 * region, select a base address on a
669 * 64-Kbyte boundary. Also, select the
670 * region size as a power-of-two if at
