config SOC_AMD_COMMON_BLOCK_SPI
	bool
	help
	  Select this option to add FCH SPI controller functions to the build.
	  This overwrites the structure spi_flash_ops to use FCH SPI code
	  instead of individual SPI specific code.

config SOC_AMD_COMMON_BLOCK_SPI_DEBUG
	bool "Enable SPI debugging"

config SOC_AMD_COMMON_BLOCK_SPI_4DW_BURST
	bool
	depends on !SOC_AMD_STONEYRIDGE
	help
	  Select this option to keep the 4 DWORD burst support enabled.

config EFS_SPI_READ_MODE

	default 2
	help
	  SPI read mode to be programmed by the PSP.
	  The numbers in the options below indicate how many wires
	  are utilized for command, address and data. For instance 1-1-2
	  means 1 command, 1 address and 2 data wires.
	    0: Normal Read (up to 33M)
	    1: Reserved
	    2: Dual IO (1-1-2)
	    3: Quad IO (1-1-4)
	    4: Dual IO (1-2-2)
	    5: Quad IO (1-4-4)
	    6: Normal Read (up to 66M)
	    7: Fast Read

	help
	  For Family 17h Model 00h and later SoC the PSP must be aware if a Micron
	  part is present in EFS. Automatic detection (option 2) is available
	  for Family 17h Model 30h-3Fh but is unsupported otherwise.
	    0: Board does not use Micron parts
	    1: Board always uses Micron parts
	    2: Micron parts are optional
