Nicolas Boulenguez e15591aaf4 fix(cert_create): let distclean Makefile target remove the cert_create tool
For some targets, Make recursively invokes itself in subdirectories.
When delegating the distclean target to tools/cert_create/Makefile,
the submake is called with the clean target instead of realclean.
Because of this, the submake never removes the cert_create executable.

A proper but more intrusive fix would
* avoid confusion about the semantics by following traditions or using
  new names
  https://www.gnu.org/prep/standards/standards.html#Standard-Targets
* avoid typing errors with the special $@ variable.
Something like:

In tools/cert_create/Makefile:
mostlyclean:
  # Remove most objects but keep some results.
        $(call SHELL_DELETE_ALL, src/build_msg.o ${OBJECTS})
clean: mostlyclean
  # mostlyclean, then remove things built by Make.
        $(call SHELL_DELETE,${BINARY})
distclean: clean
  # clean, then remove things built by ./configure (none here).
realclean maintainer-clean: distclean
  # distclean, then remove things built by autootols (none here).

In Makefile:
mostlyclean clean distclean realclean maintainer-clean:
	$(MAKE) -C subdir1 $@
	$(MAKE) -C subdir2 $@

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:

-  `Power State Coordination Interface (PSCI)`_
-  `Trusted Board Boot Requirements CLIENT (TBBR-CLIENT)`_
-  `SMC Calling Convention`_
-  `System Control and Management Interface (SCMI)`_
-  `Software Delegated Exception Interface (SDEI)`_

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.
