Dear all,
Per my understanding, newer aarch64 toolchain enable fix cortex-a53-843419
when configuring, but this only means gcc will pass "--fix-cortex-a53-843419"
to ld by default, however the linux kernel LD cmd ld rather than gcc, so
do we need to add something like the following into arch/arm64/Makefile?
ifeq ($(CONFIG_ARM64_ERRATUM_843419), y)
LDFLAGS_vmlinux += $(call ld-option, --fix-cortex-a53-843419)
endif
Thanks,
Jisheng
