config SPI_FLASH
bool
default y if BOOT_DEVICE_SPI_FLASH
default n
help
Select this option if your chipset driver needs to store certain
data in the SPI flash.
if SPI_FLASH
# Keep at 0 because lots of boards assume this default.
config BOOT_DEVICE_SPI_FLASH_BUS
int
default 0
help
Which SPI bus the boot device is connected to.

default n if COMMON_CBFS_SPI_WRAPPER
default y
config SPI_ATOMIC_SEQUENCING
bool
default y if ARCH_X86
default n if !ARCH_X86
help
Select this option if the SPI controller uses "atomic sequencing."
Atomic sequencing is when the sequence of commands is pre-programmed
in the SPI controller. Hardware manages the transaction instead of
software. This is common on x86 platforms.

bool "SPI flash driver support in SMM"
default n
depends on HAVE_SMI_HANDLER
help
Select this option if you want SPI flash support in SMM.
config SPI_FLASH_NO_FAST_READ
bool "Disable Fast Read command"
default n
help
Select this option if your setup requires to avoid "fast read"s
from the SPI flash parts.
config SPI_FLASH_ADESTO
bool
default y if SPI_FLASH_INCLUDE_ALL_DRIVERS
help
Select this option if your chipset driver needs to store certain
data in the SPI flash and your SPI flash is made by Adesto Technologies.
config SPI_FLASH_AMIC
bool
default y if SPI_FLASH_INCLUDE_ALL_DRIVERS
help
Select this option if your chipset driver needs to store certain
data in the SPI flash and your SPI flash is made by AMIC.
config SPI_FLASH_ATMEL
bool
default y if SPI_FLASH_INCLUDE_ALL_DRIVERS
help
Select this option if your chipset driver needs to store certain
data in the SPI flash and your SPI flash is made by Atmel.
