798 * Description: Test the address bus wiring in a

805 * address and size of the region are
806 * selected by the caller.
808 * Notes: For best results, the selected base
809 * address should have enough LSB 0's to
810 * guarantee single address bit changes.
811 * For example, to test a 64-Kbyte
812 * region, select a base address on a
813 * 64-Kbyte boundary. Also, select the
814 * region size as a power-of-two if at
