Hello,

While reviewing all the compiler flags used by TF-A, we couldn’t find information for the following options in the GCC manual [1]

--fatal-warnings (https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/+/refs/heads/master/Makefile#353)
-fno-stack-protector (https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/+/refs/heads/master/lib/stack_protector/stack_protector.mk#15)

Can someone please help me understand if these options are still valid?

Thanks.
