792 * Description: Test the address bus wiring in a

799 * address and size of the region are
800 * selected by the caller.
802 * Notes: For best results, the selected base
803 * address should have enough LSB 0's to
804 * guarantee single address bit changes.
805 * For example, to test a 64-Kbyte
806 * region, select a base address on a
807 * 64-Kbyte boundary. Also, select the
808 * region size as a power-of-two if at
