help
Enable this option, software will initialize SPI flash clock and I/O mode at bootloader instead of at APP.
So it will speed up system starting and reduce the time cost at loading firmware.
If your system bootloader is based on v3.0, the option must not be enable, because the v3.0 bootloader don't support
this function.
