* Description: Test the address bus wiring in a

* memory region by performing a walking
788
* 1's test on the relevant bits of the

* address and checking for aliasing.
790

* address failures such as stuck-high,
792
* stuck-low, and shorted pins. The base
793
* address and size of the region are
794
* selected by the caller.
796
* Notes: For best results, the selected base
797
* address should have enough LSB 0's to
798
* guarantee single address bit changes.
799
* For example, to test a 64-Kbyte
800
* region, select a base address on a
801
* 64-Kbyte boundary. Also, select the
802
* region size as a power-of-two if at
