788 * Description: Test the address bus wiring in a

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