<p dir="auto" style="color: #28272d; margin: 0;" align="initial">When running Zynq on Xilinx QEMU (xilinx_zynq_a9_qemu) using the arm-generic-fdt-7series machine model for SMP support, QEMU starts both cores simultaneously causing the second core to enable the MMU before the page tables are configured. It then encounters repeating prefetch aborts. This fixes that by forcing the second core to wait until the first core is ready for it to start. The new code is only present on the QEMU BSP variant.</p>
