| 822 | * Address line test |

| 824 | * Description: Test the address bus wiring in a |
| 825 | * memory region by performing a walking |
| 826 | * 1's test on the relevant bits of the |
| 827 | * address and checking for aliasing. |
| 828 | * This test will find single-bit |
| 829 | * address failures such as stuck -high, |
| 830 | * stuck-low, and shorted pins. The base |
| 831 | * address and size of the region are |
| 832 | * selected by the caller. |
| 833 | * |
| 834 | * Notes: For best results, the selected base |
| 835 | * address should have enough LSB 0's to |
| 836 | * guarantee single address bit changes. |
| 837 | * For example, to test a 64-Kbyte |
| 838 | * region, select a base address on a |
| 839 | * 64-Kbyte boundary. Also, select the |
| 840 | * region size as a power-of-two if at |
| 841 | * all possible. |
| 842 | * |
| 843 | * Returns: 0 if the test succeeds, 1 if the test fails. |
