      Linux boot time is the time length measured from the loading of Zeroth Stage Boot Loader (ZSBL) to the Linux user log-in prompt from the time the PolarFire SoC device is powered on. The PolarFire SoC boot sequence is simple and does not affect the overall performance by avoiding complex boot loader and kernel configurations. This white paper
