feat(s32g274a): add S32G274ARDB2 board support
S32G274ARDB2 is a development board to showcase the capabilities of the
S32G2 SoC. It includes 4 ARM Cortex-A53 cores running at 1.0GHz, 4GBs
of DDR, accelerators for automotive networking and many other
peripherals.
The added support is minimal and only includes the BL2 stage, with no
MMU enabled. The FIP is preloaded by the BootROM in SRAM, and BL2 copies
BL31 and BL33 from FIP to their designated addresses.

+NXP S32G274A
+============
+
+S32G2 is an NXP vehicle network processor combining ASIL D safety, hardware
+security, high-performance real-time and application processing and network
+acceleration. S32G2 supports the needs of new vehicle architectures:
+service-oriented gateways, domain controllers, zonal processors, safety
+processors and more. It is equipped with 4 Cortex-A53 cores operating at
+1.0GHz.
+
+The TF-A includes support for one single S32G2-based board called S32G274ARDB2.
+The S32G-VNP-RDB2 is a compact, highly optimized and integrated board
+engineering for vehicle service-oriented gateway (SoG), domain control
+applications, high-performance processing, safety and security applications.
+More details about this board can be found at `s32g274ardb2`_.
+
+Boot Flow
+---------
+
+::
+
+ BootROM -> BL2 (SRAM) -> BL31 (SRAM) -> BL33 (DDR - TODO)
+
+.. warning::
+ This boot flow is a preliminary version that will serve as a foundation for
+ upcoming S32G2 contributions. The execution will hang after the BL31 stage
+ due to U-Boot being deployed in SRAM instead of DDR. This issue will be
+ resolved with the addition of the DDR driver.
+
+Code Locations
+--------------
+
+- Downstream TF-A:
+ `link: <https://github.com/nxp-auto-linux/arm-trusted-firmware>`__
+
+- Downstream U-Boot:
+ `link <https://github.com/nxp-auto-linux/u-boot>`__
+
+- Downstream Linux:
+ `link <https://github.com/nxp-auto-linux/linux>`__
+
+How to build
+------------
+
+The port currently available on the S32G274ARDB2 platform is in its initial
+stage. This means that important drivers like DDR and storage are not yet
+available. Consequently, the boot process depends on BootROM to load all TF-A
+stages in SRAM. To create a bootable image, the script below should be used.
+This script makes use of the ``mkimage`` tool, which is part of the U-Boot drop
+for S32G274A SoCs.
+
+.. code:: bash
