In OSPI boot mode, a single OSPI flash (8-bit data bus configuration) or a dual-stacked OSPI flash (8-bit data bus configuration) can boot the device.
For details on OSPI flash device support, see the Vivado Design Suite User Guide: Programming and Debugging (UG908).
Note: The Boot Search Limit section describes
