Once there's a x86_64 FSP this needs to default to n. 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 select FSP_FULL_FD 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 ADD_FSP_BINARIES bool "Add Intel FSP 2.0 binaries to CBFS" if !FSP_USE_REPO default y if FSP_USE_REPO help Add the FSP-M and FSP-S binaries to CBFS. config FSP_T_CBFS string "Name of FSP-T in CBFS" depends on FSP_CAR default "fspt.bin" config FSP_T_LOCATION hex default 0xfffe0000 help The location for FSP-T. config FSP_S_CBFS string "Name of FSP-S in CBFS" default "fsps.bin" config FSP_M_CBFS string "Name of FSP-M in CBFS" default "fspm.bin" config FSP_FULL_FD bool "Use a combined FSP FD file" if !FSP_USE_REPO depends on ADD_FSP_BINARIES help Use a combined FSP FD file instead of specifying individual, already split binaries and split the file at build-time. config FSP_FD_PATH string "Location of FSP FD file" if FSP_FULL_FD && !FSP_USE_REPO help Path to the FSP FD file that contains the individual FSP-T, FSP-M and FSP-S binaries. The file gets split at build-time. config FSP_T_FILE string "Intel FSP-T (temp RAM init) binary path and filename" if !FSP_FULL_FD depends on ADD_FSP_BINARIES depends on FSP_CAR default "\$(obj)/Fsp_T.fd" if FSP_FULL_FD help The path and filename of the Intel FSP-T binary for this platform. config FSP_M_FILE string "Intel FSP-M (memory init) binary path and filename" if !FSP_FULL_FD depends on ADD_FSP_BINARIES default "\$(obj)/Fsp_M.fd" if FSP_FULL_FD 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" if !FSP_FULL_FD depends on ADD_FSP_BINARIES default "\$(obj)/Fsp_S.fd" if FSP_FULL_FD help The path and filename of the Intel FSP-S binary for this platform. config FSP_CAR bool default n select NO_CBFS_MCACHE if !NO_FSP_TEMP_RAM_EXIT help Use FSP APIs to initialize & Tear Down the Cache-As-Ram config FSP_T_RESERVED_SIZE hex default 0x100 if FSP_CAR default 0x0 help This is the size of the area reserved by FSP-T.

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 help The amount of memory coreboot reserves for the FSP to use. In the case of FSP 2.1 and newer that share the stack with coreboot instead of having its own stack, this is the amount of anticipated heap usage in CAR by FSP to setup HOB and needs to be the recommended value from the Platform FSP integration guide. In the case of the FSP having its own stack that will be placed in DRAM and not in CAR, this is the amount of memory the FSP needs for its stack and heap. 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 HAVE_FSP_LOGO_SUPPORT bool default n config BMP_LOGO bool "Enable logo" default n depends on HAVE_FSP_LOGO_SUPPORT help Uses the FSP to display the boot logo. This method supports a BMP file only. The uncompressed size can be up to 1 MB.

Default is unsupported. config SOC_INTEL_COMMON_FSP_RESET bool help Common code block to handle platform reset request raised by FSP. The FSP will use the FSP EAS v2.0 section 12.2.2 (OEM Status Code) to indicate that a reset is required. config FSPS_HAS_ARCH_UPD bool help SoC users must select this Kconfig if the `FSPS_UPD` header has architecture UPD structure as `FSPS_ARCH_UPD`. Typically, platform with FSP 2.2 specification onwards has support for `FSPS_ARCH_UPD` section as part of `FSPS_UPD` structure. But there are some exceptions as in TGL, JSL, XEON_SP FSP header doesn't have support for FSPS_ARCH_UPD. config FSPS_USE_MULTI_PHASE_INIT bool help SoC users to select this Kconfig to set EnableMultiPhaseSiliconInit to enable and execute FspMultiPhaseSiInit() API. config USE_FSP_NOTIFY_PHASE_POST_PCI_ENUM bool help The FSP API is used to notify the FSP about different phases in the boot process. The current FSP specification supports three notify phases: - Post PCI enumeration - Ready to Boot - End of Firmware This option allows FSP to execute Notify Phase API (Post PCI enumeration). SoC users can override this config to use coreboot native implementations to perform the required lock down and chipset register configuration prior to executing any 3rd-party code during PCI enumeration (i.e. Option ROM). coreboot native implementation to skip FSP Notify Phase (Post PCI enumeration) is still WIP. config USE_FSP_NOTIFY_PHASE_READY_TO_BOOT bool help The FSP API is used to notify the FSP about different phases in the boot process. The current FSP specification supports three notify phases: - Post PCI enumeration - Ready to Boot - End of Firmware This option allows FSP to execute Notify Phase API (Ready to Boot). SoC users can override this config to use coreboot native implementations to perform the required lock down and chipset register configuration prior boot to payload. config USE_FSP_NOTIFY_PHASE_END_OF_FIRMWARE bool help The FSP API is used to notify the FSP about different phases in the boot process. The current FSP specification supports three notify phases: - Post PCI enumeration - Ready to Boot - End of Firmware This option allows FSP to execute Notify Phase API (End of Firmware). SoC users can override this config to use coreboot native implementations to perform the required lock down and chipset register configuration prior boot to payload. config FSP_USES_CB_DEBUG_EVENT_HANDLER bool default n help This option allows to create `Debug Event Handler` to print FSP debug messages to output device using coreboot native implementation. endif
