config SPI_FLASH
	bool
	default n
	help
	  Select this option if your chipset driver needs to store certain
	  data in the SPI flash.

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
	default y if ARCH_X86
	default n if !ARCH_X86
	help
	  Inform system if SPI is memory-mapped or not.
