654 * Address line test
655
656 * Description: Test the address bus wiring in a
657 * memory region by performing a walking
658 * 1's test on the relevant bits of the
659 * address and checking for aliasing.
660 * This test will find single-bit
661 * address failures such as stuck-high,
662 * stuck-low, and shorted pins. The base
663 * address and size of the region are
664 * selected by the caller.
665
666 * Notes: For best results, the selected base
667 * address should have enough LSB 0's to
668 * guarantee single address bit changes.
669 * For example, to test a 64-Kbyte
670 * region, select a base address on a
671 * 64-Kbyte boundary. Also, select the
672 * region size as a power-of-two if at
673 * all possible.
674 *
675 * Returns: 0 if the test succeeds, 1 if the test fails.
