	select SOC_INTEL_COMMON_BLOCK_P2SB
	help
	  Use this config to allow common CSE block to make HECI1 function disable
	  in the SMM mode. From CNL PCH onwards,`HECI1` disabling can only be done
	  using the non-posted sideband write after FSP-S sets the postboot_sai
	  attribute.

config SOC_INTEL_COMMON_BLOCK_HECI1_DISABLE_USING_PMC_IPC
	bool
	default n
	select SOC_INTEL_COMMON_BLOCK_PMC
	help
	  Use this config to allow common CSE block to make HECI1 function disable
	  using PMC IPC command `0xA9`. From TGL PCH onwards, disabling heci1
	  device using PMC IPC doesn't required to run the operation in SMM.

config SOC_INTEL_COMMON_BLOCK_HECI1_DISABLE_USING_PCR

	  Use this config for SoC platform prior to CNL PCH (with postboot_sai implemented)

config SOC_INTEL_STORE_CSE_FPT_PARTITION_VERSION
	bool
	default n
	depends on DRIVERS_INTEL_ISH
	help
	  This configuration option stores CSE FPT partitions' version in CBMEM memory.
	  This information can be used to identify the currently running firmware partition
	  version.

	  The cost of sending HECI command to read the CSE FPT is significant (~200ms)
	  hence, the idea is to read the CSE RW version on every cold reset (to cover
	  the CSE update scenarios) and store into CBMEM to avoid the cost of resending
	  the HECI command in all consecutive warm boots.

	  Later boot stages can just read the CBMEM ID to retrieve the ISH version if
	  required.

	  Additionally, ensure this feature is platform specific hence, only enabled
	  for the platform that would like to store the ISH version into the CBMEM and
	  parse to perform some additional work.

config SOC_INTEL_CSE_SEND_EOP_EARLY
	bool "CSE send EOP early"
	depends on SOC_INTEL_COMMON_BLOCK_CSE
	help
	  Use this config to send End Of Post (EOP) earlier through SoC code in order to
	  reduce time required to send EOP and getting CSE response.
	  In later stages, CSE might be busy and might require more time to process EOP command.
	  SoC can use this Kconfig to send EOP earlier by itself.

config SOC_INTEL_CSE_SEND_EOP_LATE
	bool
	depends on SOC_INTEL_COMMON_BLOCK_CSE
	help
	  Use this config to send End Of Post (EOP) late (even after CSE `final` operation)
	  using boot state either `BS_PAYLOAD_BOOT` or `BS_PAYLOAD_LOAD` from common code
	  in order to reduce time required to send EOP and getting CSE response.
	  It has been observed that CSE might be busy and might require more time to
	  process the EOP command.
	  SoC can use this Kconfig to send EOP later by itself.
	  Starting with Jasper Lake, coreboot sends EOP before loading payload hence, this
	  config is applicable for those platforms.

config SOC_INTEL_CSE_SEND_EOP_ASYNC
	bool
	depends on SOC_INTEL_COMMON_BLOCK_CSE
	depends on !SOC_INTEL_CSE_SEND_EOP_LATE
	depends on !SOC_INTEL_CSE_SEND_EOP_EARLY
	help
	  Use this config to handle End Of Post (EOP) completion
	  asynchronously. The EOP command is sent first and the result
	  is checked later leaving time to CSE to complete the
	  operation while coreboot perform other activities.
	  Performing EOP asynchronously reduces the time spent
	  actively waiting for command completion which can have a
	  significant impact on boot time.

	  Using this asynchronous approach comes with the limitation
	  that no HECI command should be sent between the time the EOP
	  request is posted (at CSE .final device operation) and the
	  time coreboot check for its completion (BS_PAYLOAD_LOAD).
