+OpenPiton FPGA SoC Platform
+========================
+OpenPiton is the world's first open source, general purpose, multithreaded
+manycore processor. It is a tiled manycore framework scalable from one to
+1/2 billion cores. Currently, OpenPiton supports the 64bit Ariane RISC-V
+processor from ETH Zurich. To this end, Ariane has been equipped with a
+different L1 cache subsystem that follows a write-through protocol and that has
+support for cache invalidations and atomics.
+
+To build platform specific library and firmwares, provide the
+*PLATFORM=fpga/openpiton* parameter to the top level `make` command.
+
+Platform Options
+----------------
+
+The *OpenPiton* platform does not have any platform-specific options.
+
+Building Ariane FPGA Platform
+-----------------------------
+
+**Linux Kernel Payload**
+
+```
+make PLATFORM=fpga/openpiton FW_PAYLOAD_PATH=<linux_build_directory>/arch/riscv/boot/Image
+```
+
+Booting Ariane FPGA Platform
+----------------------------
+
+**Linux Kernel Payload**
+
+As Linux kernel image is embedded in the OpenSBI firmware binary, Ariane will
+directly boot into Linux directly after powered on.
