This enables SPI and SPI flash in TPL. Without the this only
|
|
available boot method is to use memory-mapped SPI. Since this is
|
|
actually fast and produces a TPL which is 7KB smaller, memory-mapped
|
|
SPI is the default.

help
|
|
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.
