	bool "SiFive errata"
	depends on !XIP_KERNEL
	select RISCV_ALTERNATIVE
	help
	  All SiFive errata Kconfig depend on this Kconfig. Disabling
	  this Kconfig will disable all SiFive errata. Please say "Y"
	  here if your platform uses SiFive CPU cores.

	  Otherwise, please say "N" here to avoid unnecessary overhead.

config ERRATA_SIFIVE_CIP_453
	bool "Apply SiFive errata CIP-453"
	depends on ERRATA_SIFIVE && 64BIT
	default y
	help
	  This will apply the SiFive CIP-453 errata to add sign extension
	  to the $badaddr when exception type is instruction page fault
	  and instruction access fault.

	  If you don't know what to do here, say "Y".

config ERRATA_SIFIVE_CIP_1200
	bool "Apply SiFive errata CIP-1200"
	depends on ERRATA_SIFIVE && 64BIT
	default y
	help
	  This will apply the SiFive CIP-1200 errata to repalce all
	  "sfence.vma addr" with "sfence.vma" to ensure that the addr
	  has been flushed from TLB.

	  If you don't know what to do here, say "Y".

config ERRATA_THEAD
	bool "T-HEAD errata"
	depends on !XIP_KERNEL
	select RISCV_ALTERNATIVE
	help
	  All T-HEAD errata Kconfig depend on this Kconfig. Disabling
	  this Kconfig will disable all T-HEAD errata. Please say "Y"
	  here if your platform uses T-HEAD CPU cores.

	  Otherwise, please say "N" here to avoid unnecessary overhead.

config ERRATA_THEAD_PBMT
	bool "Apply T-Head memory type errata"
	depends on ERRATA_THEAD && 64BIT
	select RISCV_ALTERNATIVE_EARLY
	default y
	help
	  This will apply the memory type errata to handle the non-standard
	  memory type bits in page-table-entries on T-Head SoCs.

	  If you don't know what to do here, say "Y".
