787 * Description: Test the address bus wiring in a

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