780 * Description: Test the address bus wiring in a

782 * 1's test on the relevant bits of the

784 * This test will find single-bit
785 * address failures such as stuck -high,
786 * stuck-low, and shorted pins. The base
787 * address and size of the region are
788 * selected by the caller.
790 * Notes: For best results, the selected base
791 * address should have enough LSB 0's to
792 * guarantee single address bit changes.
793 * For example, to test a 64-Kbyte
794 * region, select a base address on a
795 * 64-Kbyte boundary. Also, select the
796 * region size as a power-of-two if at
799 * Returns: 0 if the test succeeds, 1 if the test fails.

802 * addresses such that addr_mask has
803 * lots of bits set. For example an
804 * address range of 01000000 02000000 is
805 * bad while a range of 01000000
