Jayanth Dodderi Chidanand c5e1da836c refactor(build): cleanup Makefile to handle build flags precisely
Presently, Makefile is unsystematic with no precise ordering
of configuration and commands.
This patch addresses this issue, by sorting and arranging the related
sections in an order, which helps in maintaining it precisely.
Further, this assists developers in identifying the concerned section
and add related changes appropriately with ease.

Additionally, SIMICS build option linked to Intel platform, has been
removed, as there is no platform specific support to utilise it.

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.
