From d32113c7f3d291b35e0debdccac609c88a0343ae Mon Sep 17 00:00:00 2001 From: Arunachalam Ganapathy Date: Mon, 27 Jul 2020 13:51:30 +0100 Subject: plat: arm: Make BL32_BASE platform dependent when SPD_spmd is enabled To support platforms without Trusted DRAM this patch defines PLAT_ARM_SPMC_BASE and enables platform to use either Trusted DRAM or DRAM region behind TZC.
