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.
