823 * Description: Test the address bus wiring in a

833 * Notes: For best results, the selected base
834 * address should have enough LSB 0's to
835 * guarantee single address bit changes.
836 * For example, to test a 64-Kbyte
837 * region, select a base address on a
838 * 64-Kbyte boundary. Also, select the
839 * region size as a power-of-two if at
