818 | * memory region by performing a walking | |
819 | * 1's test on the relevant bits of the | |
820 | * address and checking for aliasing. | |
821 | * This test will find single-bit | |
822 | * address failures such as stuck -high, | |
823 | * stuck-low, and shorted pins. The base | |
824 | * address and size of the region are | |
825 | * selected by the caller. | |
826 | * | |
827 | * Notes: For best results, the selected base | |
828 | * address should have enough LSB 0's to | |
829 | * guarantee single address bit changes. | |
830 | * For example, to test a 64-Kbyte | |
831 | * region, select a base address on a | |
832 | * 64-Kbyte boundary. Also, select the | |
833 | * region size as a power-of-two if at | |
834 | * all possible. | |
835 | * | |
836 | * Returns: 0 if the test succeeds, 1 if the test fails. | |

839 | * addresses such that addr_mask has | |
840 | * lots of bits set. For example an | |
