781 * Description: Test the address bus wiring in a

783 * 1's test on the relevant bits of the

785 * This test will find single-bit

787 * stuck-low, and shorted pins. The base
788 * address and size of the region are
789 * selected by the caller.
791 * Notes: For best results, the selected base
792 * address should have enough LSB 0's to
793 * guarantee single address bit changes.
794 * For example, to test a 64-Kbyte
795 * region, select a base address on a
796 * 64-Kbyte boundary. Also, select the
797 * region size as a power-of-two if at

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