From 10c669585456bc9122bb86c1710e80599f5eae89 Mon Sep 17 00:00:00 2001 From: Etienne Carriere Date: Mon, 5 Feb 2018 10:42:42 +0100 Subject: aarch32: optee: define the OP-TEE secure payload AArch32 only platforms can boot the OP-TEE secure firmware as a BL32 secure payload. Such configuration can be defined through AARCH32_SP=optee. The source files can rely on AARCH32_SP_OPTEE to condition OP-TEE boot specific instruction sequences. OP-TEE does not expect ARM Trusted Firmware formatted structure as boot argument. Load sequence is expected to have already loaded to OP-TEE boot arguments into the bl32 entrypoint info structure. Last, AArch32 platform can only boot AArch32 OP-TEE images.
