Masahiro Yamada 9cefb4b194 Pass more -D options to BL*_CPPFLAGS instead of BL*_CFLAGS 
Commit d5e97a1d2c ("Build: define IMAGE_AT_EL1 or IMAGE_AT_EL3
globally for C files") does not have commit 848a7e8ce1 ("Build:
introduce per-BL CPPFLAGS and ASFLAGS") as an ancestor because
they were pulled almost at the same time.

This is a follow-up conversion to be consistent with commit
11a3c5ee73 ("plat: pass -D option to BL*_CPPFLAGS instead of
BL*_CFLAGS").

With this change, the command line option, IMAGE_AT_EL3, will be
passed to .S files as well.

I remove the definition in include/lib/cpus/aarch64/cpu_macros.S

Otherwise, the following error would happen.

  include/lib/cpus/aarch64/cpu_macros.S:29:0: error: "IMAGE_AT_EL3" redefined [-Werror]

Trusted Firmware-A

Trusted Firmware-A (TF-A) is a reference implementation of secure world software for Arm A-Profile architectures (Armv8-A and Armv7-A), including an Exception Level 3 (EL3) Secure Monitor. It provides a suitable starting point for productization of secure world boot and runtime firmware, in either the AArch32 or AArch64 execution states.

TF-A implements Arm interface standards, including:

The code is designed to be portable and reusable across hardware platforms and software models that are based on the Armv8-A and Armv7-A architectures.

In collaboration with interested parties, we will continue to enhance TF-A with reference implementations of Arm standards to benefit developers working with Armv7-A and Armv8-A TrustZone technology.

Users are encouraged to do their own security validation, including penetration testing, on any secure world code derived from TF-A.
