- The path and filename of the Intel FSP binary for this platform.

-config FSP_LOC
- hex "Intel FSP Binary location in CBFS"
- help
- The location in CBFS that the FSP is located. This must match the
- value that is set in the FSP binary. If the FSP needs to be moved,
- rebase the FSP with Intel's BCT (tool).
-
-config ENABLE_FSP_FAST_BOOT
- bool "Enable Fast Boot"
- select ENABLE_MRC_CACHE

- Enabling this feature will force the MRC data to be cached in NV
- storage to be used for speeding up boot time on future reboots
- and/or power cycles.
-
-config ENABLE_MRC_CACHE
- bool
- default y if HAVE_ACPI_RESUME
- default n
- help
- Enabling this feature will cause MRC data to be cached in NV storage.
- This can either be used for fast boot, or just because the FSP wants
- it to be saved.
-
-config MRC_CACHE_FMAP
- bool "Use MRC Cache in FMAP"
- depends on ENABLE_MRC_CACHE
- select CACHE_MRC_SETTINGS
- default n
- help
- Use the region "RW_MRC_CACHE" in FMAP instead of "mrc.cache" in CBFS.

- depends on !MRC_CACHE_FMAP
- help
- This is the amount of space in NV storage that is reserved for the
- fast boot data cache storage.
-
- WARNING: Because this area will be erased and re-written, the size
- should be a full sector of the flash ROM chip and nothing else should
- be included in CBFS in any sector that the fast boot cache data is in.
-
-config VIRTUAL_ROM_SIZE
- hex "Virtual ROM Size"
- default ROM_SIZE
- depends on ENABLE_MRC_CACHE
- help
- This is used to calculate the offset of the MRC data cache in NV
- Storage for fast boot. If in doubt, leave this set to the default
- which sets the virtual size equal to the ROM size.
-
- Example: Cougar Canyon 2 has two 8 MB SPI ROMs. When the SPI ROMs are
- loaded with a 4 MB coreboot image, the virtual ROM size is 8 MB. When
- the SPI ROMs are loaded with an 8 MB coreboot image, the virtual ROM
- size is 16 MB.
-
-config USE_GENERIC_FSP_CAR_INC
- bool
- default n
- help
- The chipset can select this to use a generic cache_as_ram.inc file
- that should be good for all FSP based platforms.
-
-config FSP_USES_UPD
- bool
- default n
- help
- If this FSP uses UPD/VPD data regions, select this in the chipset Kconfig.
