Support for NXP's i.MX8QX SoC 

NXP's i.MX8QX is an ARMv8 SoC with 4 Cortex-A35 cores and
system controller (Cortex-M4) inside, documentation can
be found in below link:

https://www.nxp.com/products/processors-and-microcontrollers/
applications-processors/i.mx-applications-processors/i.mx-8-processors:IMX8-SERIES

This patch adds support for booting up SMP linux kernel (v4.9).

Description
===========
The i.MX 8 series of applications processors is a feature- and
performance-scalable multi-core platform that includes single-,
dual-, and quad-core families based on the Arm® Cortex®
architecture—including combined Cortex-A72 + Cortex-A53,
Cortex-A35, and Cortex-M4 based solutions for advanced graphics,
imaging, machine vision, audio, voice, video, and safety-critical
applications.
The i.MX8QX is with 4 Cortex-A35 ARM core and 1 Cortex-M4 system
controller.
The System Controller (SC) represents the evolution of centralized
control for system-level resources on i.MX8. The heart of the system
controller is a Cortex-M4 that executes system controller firmware.
Boot Sequence
=============
Bootrom --> BL31 --> BL33(u-boot) --> Linux kernel
How to build
============
Build Procedure
---------------
- Prepare AARCH64 toolchain.
- Build System Controller Firmware and u-boot firstly, and get binary images: scfw_tcm.bin and u-boot.bin
- Build TF-A
Build bl31:
.. code:: shell
CROSS_COMPILE=aarch64-linux-gnu- make PLAT=<Target_SoC> bl31
Target_SoC should be "imx8qx" for i.MX8QX SoC.
Deploy TF-A Images
-----------------
TF-A binary(bl31.bin), scfw_tcm.bin and u-boot.bin are combined together
to generate a binary file called flash.bin, the imx-mkimage tool is used
to generate flash.bin, and flash.bin needs to be flashed into SD card
with certain offset for BOOT ROM. The system controller firmware,
u-boot and imx-mkimage will be upstreamed soon, this doc will be updated
once they are ready, and the link will be posted.
