657 * Description: Test the address bus wiring in a

661 * This test will find single-bit
662 * address failures such as stuck-high,
663 * stuck-low, and shorted pins. The base
664 * address and size of the region are
665 * selected by the caller.
667 * Notes: For best results, the selected base
668 * address should have enough LSB 0's to
669 * guarantee single address bit changes.
670 * For example, to test a 64-Kbyte
671 * region, select a base address on a
672 * 64-Kbyte boundary. Also, select the
673 * region size as a power-of-two if at
