+Intel Agilex SoCFPGA
+========================
+
+Agilex SoCFPGA is a FPGA with integrated quad-core 64-bit Arm Cortex A53 processor.
+
+Upon boot, Boot ROM loads bl2 into OCRAM. Bl2 subsequently initializes
+the hardware, then loads bl31 and bl33 (UEFI) into DDR and boots to bl33.
+
+::
+
+    Boot ROM --> Trusted Firmware-A --> UEFI
+
+How to build
+------------
+
+Code Locations
+~~~~~~~~~~~~~~
+
+-  Trusted Firmware-A:
+   `link <https://github.com/ARM-software/arm-trusted-firmware>`__
+
+-  UEFI (to be updated with new upstreamed UEFI):
+   `link <https://github.com/altera-opensource/uefi-socfpga>`__
+
+Build Procedure
+~~~~~~~~~~~~~~~
+
+-  Fetch all the above 2 repositories into local host.
+   Make all the repositories in the same ${BUILD\_PATH}.
+
+-  Prepare the AARCH64 toolchain.
+
+-  Build UEFI using Agilex platform as configuration
+   This will be updated to use an updated UEFI using the latest EDK2 source
+
+.. code:: bash
+
+       make CROSS_COMPILE=aarch64-linux-gnu- device=agx
+
+-  Build atf providing the previously generated UEFI as the BL33 image
+
+.. code:: bash
+
+       make CROSS_COMPILE=aarch64-linux-gnu- bl2 fip PLAT=agilex
+       BL33=PEI.ROM
+
+Install Procedure
+~~~~~~~~~~~~~~~~~
+
+- dd fip.bin to a A2 partition on the MMC drive to be booted in Agilex
+  board.
+
+- Generate a SOF containing bl2
+
+.. code:: bash
+
+        aarch64-linux-gnu-objcopy -I binary -O ihex --change-addresses 0xffe00000 bl2.bin bl2.hex
+        quartus_cpf --bootloader bl2.hex <quartus_generated_sof> <output_sof_with_bl2>
+
+- Configure SOF to board
+
+.. code:: bash
+
+        nios2-configure-sof <output_sof_with_bl2>
+
