Add imx93-var-som support
Add support for the Variscite VAR-SOM-IMX93 evaluation kit. The SoM
consists of an NXP iMX93 dual A55 CPU. The SoM is mounted on a Variscite
Symphony SBC.

+imx93_var_som
+=======================
+
+U-Boot for the Variscite VAR-SOM-MX93 Symphony evaluation board
+
+Quick Start
+-----------
+
+- Get and Build the ARM Trusted firmware
+- Get the DDR firmware
+- Get ahab-container.img
+- Build U-Boot
+- Boot
+
+Get and Build the ARM Trusted firmware
+--------------------------------------
+
+Note: srctree is U-Boot source directory
+Get ATF from: https://github.com/nxp-imx/imx-atf/
+branch: lf_v2.8
+
+.. code-block:: bash
+
+ $ unset LDFLAGS
+ $ make PLAT=imx93 bl31
+ $ cp build/imx93/release/bl31.bin $(srctree)
+
+Get the DDR firmware
+--------------------
+
+.. code-block:: bash
+
+ $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.21.bin
+ $ chmod +x firmware-imx-8.21.bin
+ $ ./firmware-imx-8.21.bin
+ $ cp firmware-imx-8.21/firmware/ddr/synopsys/lpddr4*.bin $(srctree)
+
+Get ahab-container.img
+---------------------------------------
+
+.. code-block:: bash
+
+ $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-sentinel-0.10.bin
+ $ chmod +x firmware-sentinel-0.10.bin
+ $ ./firmware-sentinel-0.10.bin
+ $ cp firmware-sentinel-0.10/mx93a0-ahab-container.img $(srctree)
+
+Build U-Boot
+------------
+
+.. code-block:: bash
+
+ $ export CROSS_COMPILE=aarch64-poky-linux-
+ $ make imx93_var_som_defconfig
+ $ make
+
+Burn the flash.bin to MicroSD card offset 32KB:
+
+.. code-block:: bash
+
+ $ dd if=flash.bin of=/dev/sd[x] bs=1024 seek=32 conv=notrunc
+
+Boot
+----
+
+Set Boot switch to SD boot
