781 | * memory region by performing a walking | |
782 | * 1's test on the relevant bits of the | |
783 | * address and checking for aliasing. | |
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. | |
789 | * | |
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 | |
797 | * all possible. | |
798 | * | |
799 | * Returns: 0 if the test succeeds, 1 if the test fails. | |

801 | * ## NOTE ## Be sure to specify start and end | |
802 | * addresses such that addr_mask has | |
803 | * lots of bits set. For example an | |
