* 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.
