RISC-V SBI bootloader and firmware

The RISC-V Supervisor Binary Interface SBI is the recommended interface between

  1. A platform-specific firmware running in M-mode and a bootloader, a hypervisor or a general-purpose OS executing in S-mode or HS-mode.
  2. A hypervisor running in HS-mode and a bootloader or a general-purpose OS executing in VS-mode.

The RISC-V SBI specification is maintained as an independent project by the RISC-V Foundation at https//github.com/riscv/riscv-sbi-doc.

The goal of the OpenSBI project is to provide an open-source reference implementation of the RISC-V SBI specifications for platform-specific firmwares executing in M-mode case 1 mentioned above. An OpenSBI implementation can be easily extended by RISC-V platform and system-on-chip vendors to fit a particular hardware configuration.
