+         *              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
