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 int range 0 7 default 0 if EM100 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 config EFS_SPI_SPEED int range 0 5 default 3 if EM100 default 1 help SPI Fast Speed to be programmed by the PSP. 0: 66.66Mhz 1: 33.33MHz 2: 22.22MHz 3: 16.66MHz 4: 100MHz 5: 800KHz config EFS_SPI_MICRON_FLAG int range 0 2 default 0 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 config NORMAL_READ_SPI_SPEED int range 0 5 default 3 if EM100 default 1 help SPI Normal Speed to be programmed by coreboot. 0: 66.66Mhz 1: 33.33MHz 2: 22.22MHz 3: 16.66MHz 4: 100MHz 5: 800KHz config ALT_SPI_SPEED int range 0 5 default 3 if EM100 default 1 help SPI ALT Speed to be programmed by coreboot. 0: 66.66Mhz 1: 33.33MHz 2: 22.22MHz 3: 16.66MHz 4: 100MHz 5: 800KHz config TPM_SPI_SPEED int range 0 5 default 3 if EM100 default 1 help SPI TPM Speed to be programmed by coreboot. 0: 66.66Mhz 1: 33.33MHz 2: 22.22MHz 3: 16.66MHz 4: 100MHz 5: 800KHz
