+Xilinx Versal NET
+=================
+
+- The TF-A Tests on Xilinx Versal NET platform runs from DDR.
+- Logs are available only on console and not saved in memory(No NVM support).
+- Versal NET Platform uses TTC Timer
+
+Build Command
+-------------
+For individual tests/test suite:
+
+.. code-block:: shell
+        make CROSS_COMPILE=aarch64-none-elf- PLAT=versal_net TESTS=<required tests> tftf
+For Versal NET Specific tests (includes AMD-Xilinx Tests cases + Standard Test Suite)
+
+.. code-block:: shell
+        make CROSS_COMPILE=aarch64-none-elf- PLAT=versal_net TESTS=versal tftf
+
+Execution on Target
+-------------------
+
+- The TF-A Tests uses the memory location of U-boot.
+- To package the tftf.elf in BOOT.BIN, the u-boot entry in bootgen.bif needs to be replaced with following
+
+.. code-block:: shell
+        the_ROM_image:
+        {
+                image {
+                        { type=bootimage, file=project-spec/hw-description/system.pdi }
+                        { type=bootloader, file=plm.elf }
+                        { core=psm, file=psmfw.elf }
+                }
+                image {
+                        id = 0x1c000000, name=apu_subsystem
+                        { type=raw, load=0x00001000, file=system-default.dtb }
+                        { core=a78-0, exception_level=el-3, trustzone, file=bl31.elf }
+                        { core=a78-0, exception_level=el-1, file=tftf.elf }
+                }
+        }
+
+- The BOOT.BIN with TF-A Tests can now be used to run on the target.
+- The TF-A Tests will be executed after TF-A and the tests report will be available on the console.
