TF-A: TrustedFirmware-a SPM: Secure Partition Manager(MM) For AArch64, when SPM enable in TF-A, TF-A may communicate to MM with buffer address (PLAT_SPM_BUF_BASE). The address is different from PcdMmBufferBase which use in edk2. Checking address will let TF-A communicate failed to MM. So remove below checking code: if (NsCommBufferAddr < mNsCommBuffer.PhysicalStart) { return EFI_ACCESS_DENIED; }
