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 HAVE_INTEL_FSP_REPO
bool
help
Select this, if the FSP binaries for the platform are public
and available in 3rdparty/fsp/. When selecting this option, the
platform must also set FSP_HEADER_PATH and FSP_FD_PATH correctly.
config FSP_USE_REPO
bool "Use binaries of the Intel FSP repository on GitHub"
depends on HAVE_INTEL_FSP_REPO
default y
help
Select this option to use the default FSP headers and binaries
found in the IntelFsp GitHub repository at
https://github.com/IntelFsp/FSP/
If unsure, say Y.
config FSP_HEADER_PATH
string "Location of FSP headers" if !FSP_USE_REPO
help
Include directory with the FSP ABI header files.
config FSP_FD_PATH
string
depends on FSP_USE_REPO
help
Path to the FSP FD file that contains the individual FSP-T, FSP-M
and FSP-S binaries.
config ADD_FSP_BINARIES
bool "Add Intel FSP 2.0 binaries to CBFS" if !FSP_USE_REPO

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.

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.
