824 * Description: Test the address bus wiring in a

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