Subject: [edk2-platforms][PATCH v2 6/6] Platform/StandaloneMm: build StandaloneMmRpmb for 32bit architectures
Date: Mon, 17 May 2021 07:50:47 +0200 [thread overview]
Message-ID: <20210517055047.30814-6-etienne.carriere@linaro.org> (raw)
In-Reply-To: <20210517055047.30814-1-etienne.carriere@linaro.org>
Build PlatformStandaloneMmRpmb for ARM architecture (32bit arm machine).
The generated image targets an execution environment similar to AArch64
StMM secure partition in OP-TEE but in 32bit mode.
GCC flag -fno-stack-protector
added. The stack protection code bring
GOT dependencies we prefer avoid when StMM runs in OP-TEE.

Changes since v1:
- Remove useless duplication of ArmSvcLib loading.
- Move BaseStackCheckLib to generic library classes instead of ARM only.
- include MdePkg/MdeLibs.dsc.inc
instead of loading
RegisterFilterLibNull.inf for ARM architecture.
