+ This enables SPI and SPI flash in TPL. Without the this only

+ This option is separate from APL_SPI_FLASH_BOOT since it is useful to
+ be able to compare booting speed with the same build. Enable this to
+ use the SPI-flash driver to load SPL, U-Boot and FSP-M. For technical
+ reasons FSP-S is currently always loaded from memory-mapped SPI. See
+ Apollo Lake's arch_fsp_init_r() for details about that.
