Subject: [Buildroot] [PATCH 1/1] boot/arm-trusted-firmware: Forward stack protection configuration
Date: Fri, 20 Nov 2020 22:29:12 +0100 [thread overview]
Message-ID: <20201120212912.2993985-1-christoph.muellner@theobroma-systems.com> (raw)
TF-A supports stack smashing protection (-fstack-protector-*).
Since we already forward the required compiler flag, let's
also tell TF-A that we actually want the required symbols
(e.g. __stack_chk_guard) to be available.
