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
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.

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
