+Andes AE350 SoC Platform
+========================
+The AE350 AXI/AHB-based platform N25(F)/NX25(F)/D25F/A25/AX25 CPU with
+level-one memories,interrupt controller, debug module, AXI and AHB Bus
+Matrix Controller, AXI-to-AHB Bridge and a collection of fundamentalAHB/APB
+bus IP components pre-integrated together as a system design.The high-quality
+and configurable AHB/APB IPs suites a majority embedded systems,
+and the verified platform serves as a starting point to jump start SoC designs.
+
+To build platform specific library and firmwares, provide the *PLATFORM=andes/ae350* parameter to the top level make command.
+
+Platform Options
+----------------
+
+The Andes AE350 platform does not have any platform-specific options.
+
+Building Andes AE350 Platform
+-----------------------------
+
+To use Linux v5.2 should be used to build Andes AE350 OpenSBI binaries by using the compile time option FW_PAYLOAD_FDT_PATH.
