	bool
	default n
	help
	  This will send an Exit 4-Byte Address Mode (E9h) command before the first
	  access to the SPI flash. On some platforms with SPI flashes larger than 32MB,
	  the SPI flash may power up in 4-byte addressing mode and this command needs
	  to be sent before coreboot's 3-byte address commands can be interpreted correctly.
	  On flashes that don't support 4-byte addressing mode or where it is already
	  disabled, this command should be a no-op.

config SPI_FLASH_FORCE_4_BYTE_ADDR_MODE
	bool
	default n
	help
	  This will force coreboot to send addresses as 4-bytes instead of 3-bytes.
	  On some platforms with SPI flashes larger than 16MB, the SPI flash may need
	  to remain in 4-byte addressing mode.
