Did you enable CONFIG_SPI_FLASH_SPANSION on your config, becuase
S25FL512S is already been added u-boot. Pls- check the same and let me
know if you find any issues while detecting the flash.

Whether the driver detecting flash or not with RDID, please define
DEBUG on drivers/mtd/spi/spi_flash.c

thanks!
