OpenPiton is a research platform from Princeton University [1]. "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." Add OpenSBI support for OpenPiton. As it is based on ariane core, it reuses the platform code from arine project.

OpenSBI Supported Platforms
OpenSBI currently supports the following virtual and hardware platforms:
-
QEMU RISC-V Virt Machine: Platform support for the QEMU virt virtual RISC-V machine. This virtual machine is intended for RISC-V software development and tests. More details on this platform can be found in the file qemu_virt.md.
-
SiFive FU540 SoC: Platform support for SiFive FU540 SoC used on the HiFive Unleashed board, as well as the sifive_u QEMU virtual RISC-V machine. More details on this platform can be found in the file sifive_fu540.md.
-
Kendryte K210 SoC: Platform support for the Kendryte K210 SoC used on boards such as the Kendryte KD233 or the Sipeed MAIX Dock.
-
Ariane FPGA SoC: Platform support for the Ariane FPGA SoC used on Genesys 2 board.
-
Andes AE350 SoC: Platform support for the Andes's SoC (AE350).
-
T-HEAD C910: Platform support for the T-HEAD C910 Processor.
-
Spike: Platform support for the Spike emulator.
-
OpenPiton FPGA SoC: Platform support OpenPiton research platform based on ariane core.
The code for these supported platforms can be used as example to implement support for other platforms. The platform/template directory also provides template files for implementing support for a new platform. The object.mk, config.mk and platform.c template files provides enough comments to facilitate the implementation.
