config ERRATA_SIFIVE
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"
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".
