Chris Kay e04da4c8e1 build(fconf)!: clean up source collection
Including the FCONF Makefile today automatically places the FCONF
sources into the source list of the BL1 and BL2 images. This may be
undesirable if, for instance, FCONF is only required for BL31.

This change moves the BL1 and BL2 source appends out of the common
Makefile to where they are required.

BREAKING CHANGE: FCONF is no longer added to BL1 and BL2 automatically
when the FCONF Makefile (`fconf.mk`) is included. When including this
Makefile, consider whether you need to add `${FCONF_SOURCES}` and
`${FCONF_DYN_SOURCES}` to `BL1_SOURCES` and `BL2_SOURCES`.

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.
