select FSP_USES_CB_STACK
select FSP_PEIM_TO_PEIM_INTERFACE
help
Include FSP 2.1 wrappers and functionality.
Features added into FSP 2.1 specification that impacts coreboot are:
1. Remove FSP stack switch and use the same stack with boot firmware
2. FSP should support external PPI interface pulled in via FSP_PEIM_TO_PEIM_INTERFACE
if PLATFORM_USES_FSP2_0
config ADD_FSP_BINARIES
bool "Add Intel FSP 2.0 binaries to CBFS"
help
Add the FSP-M and FSP-S binaries to CBFS. Currently coreboot does not
use the FSP-T binary and it is not added.
config DISPLAY_FSP_CALLS_AND_STATUS
bool "Display the FSP calls and status"
default n
help
Display the FSP call entry point and parameters prior to calling FSP
and display the status upon return from FSP.
config DISPLAY_FSP_HEADER
bool "Display the FSP header"
default n
help
Display the FSP header information when the FSP file is found.
config DISPLAY_HOBS
bool "Display the hand-off-blocks"
default n
help
Display the FSP HOBs which are provided for coreboot.
config DISPLAY_UPD_DATA
bool "Display UPD data"
default n
help
Display the user specified product data prior to memory
initialization.
config CPU_MICROCODE_CBFS_LEN
hex "Microcode update region length in bytes"
depends on FSP_CAR
default 0x0
help
The length in bytes of the microcode update region.
config CPU_MICROCODE_CBFS_LOC
hex "Microcode update base address in CBFS"
depends on FSP_CAR
default 0x0
help
The location (base address) in CBFS that contains the
microcode update binary.

depends on ADD_FSP_BINARIES
depends on SOC_INTEL_APOLLOLAKE || SOC_INTEL_SKYLAKE || \
SOC_INTEL_KABYLAKE || SOC_INTEL_COFFEELAKE || \
SOC_INTEL_WHISKEYLAKE
help
When selecting this option, the SoC must set FSP_HEADER_PATH
and FSP_FD_PATH correctly so FSP splitting works.
config FSP_T_FILE
string "Intel FSP-T (temp ram init) binary path and filename"
depends on FSP_CAR
default "$(obj)/Fsp_T.fd" if FSP_USE_REPO
help
The path and filename of the Intel FSP-M binary for this platform.
config FSP_M_FILE
string "Intel FSP-M (memory init) binary path and filename"
depends on ADD_FSP_BINARIES
default "$(obj)/Fsp_M.fd" if FSP_USE_REPO
help
The path and filename of the Intel FSP-M binary for this platform.
config FSP_S_FILE
string "Intel FSP-S (silicon init) binary path and filename"
depends on ADD_FSP_BINARIES
default "$(obj)/Fsp_S.fd" if FSP_USE_REPO
help
The path and filename of the Intel FSP-S binary for this platform.
config FSP_CAR
bool
default n
help
Use FSP APIs to initialize & Tear Down the Cache-As-Ram
config FSP_M_XIP

help
Select this value when FSP-M is execute-in-place.
config FSP_T_XIP
bool
default n
help
Select this value when FSP-T is execute-in-place.
config FSP_USES_CB_STACK
bool
default n
help
Enable support for fsp to use same stack as coreboot.
This option allows fsp to continue using coreboot stack
without reinitializing stack pointer. This feature is
supported Icelake onwards.
config FSP_TEMP_RAM_SIZE
hex
depends on FSP_USES_CB_STACK
help
The amount of anticipated heap usage in CAR by FSP to setup HOB.
This configuration is applicable for FSP specification using shared
stack with coreboot/bootloader.
Sync this value with Platform FSP integration guide recommendation.
config VERIFY_HOBS
bool "Verify the FSP hand-off-blocks"
default n
help
Verify that the HOBs required by coreboot are returned by FSP and
that the resource HOBs are in the correct order and position.
config RESET_ON_INVALID_RAMSTAGE_CACHE
bool "Reset the system on S3 wake when ramstage cache invalid."
default n
config DISPLAY_FSP_VERSION_INFO
bool "Display Firmware Ingredient Version Information"

bool
depends on TPM1 || TPM2
depends on VBOOT && VBOOT_STARTS_IN_BOOTBLOCK
default y if HAS_RECOVERY_MRC_CACHE
default n
select VBOOT_HAS_REC_HASH_SPACE
help
Store hash of trained recovery MRC cache in NVRAM space in TPM.
Use the hash to validate recovery MRC cache before using it.
This hash needs to be updated every time recovery mode training
is recomputed, or if the hash does not match recovery MRC cache.
Selecting this option requires that TPM already be setup by this
point in time. Thus it is only compatible when the option
VBOOT_STARTS_IN_BOOTBLOCK is selected, which causes verstage and
TPM setup to occur prior to memory initialization.
config FSP_PLATFORM_MEMORY_SETTINGS_VERSIONS
bool
help
This is selected by SoC or mainboard to supply their own
concept of a version for the memory settings respectively.
This allows deployed systems to bump their version number
with the same FSP which will trigger a retrain of the memory.
config FSP_PEIM_TO_PEIM_INTERFACE
bool
select FSP_USES_MP_SERVICES_PPI
help
This option allows SOC user to create specific PPI for Intel FSP
usage, coreboot will provide required PPI structure definitions
along with all APIs as per EFI specification. So far this feature
is limited till EFI_PEI_MP_SERVICE_PPI and this option might be
useful to add further PPI if required.
