- * Address line test
- *
- * Description: Test the address bus wiring in a
- * memory region by performing a walking
- * 1's test on the relevant bits of the
- * address and checking for aliasing.
- * This test will find single-bit
- * address failures such as stuck -high,
- * stuck-low, and shorted pins. The base
- * address and size of the region are
- * selected by the caller.
- *
- * Notes: For best results, the selected base
- * address should have enough LSB 0's to
- * guarantee single address bit changes.
- * For example, to test a 64-Kbyte
- * region, select a base address on a
- * 64-Kbyte boundary. Also, select the
- * region size as a power-of-two if at
- * all possible.
- *
- * Returns: 0 if the test succeeds, 1 if the test fails.
- *
- * ## NOTE ## Be sure to specify start and end
- * addresses such that addr_mask has
- * lots of bits set. For example an
- * address range of 01000000 02000000 is
- * bad while a range of 01000000
- * 01ffffff is perfect.
