See Documentation/boards/riscv.rst for instructions. You can obtain this patchseries from github: $ git clone -b 20170929.riscv https://github.com/frantony/barebox Changes since RFC v3 (20161212) (http://lists.infradead.org/pipermail/barebox/2016-December/028716.html) * drop SiFive support, add support for custom Erizo SoC; * barebox runs on real hardware (e.g. DE0-Nano FPGA board, see https://github.com/miet-riscv-workgroup/rv32-simple-soc for details); * introduce NMON for RISC-V; * add relocator to start.S. Changes since RFC v2 (20161113) (http://lists.infradead.org/pipermail/barebox/2016-November/028533.html): * add RV32 support. Changes since RFC v1 (20161013) (http://lists.infradead.org/pipermail/barebox/2016-October/028309.html): * drop spike pk support; * add qemu-sifive board support; * add Documentation/boards/riscv.rst; * fix guard macro names TODOs: * add pbl support; * sync with https://github.com/riscv/riscv-linux; * RV64 definitions are unused now; * sync MIPS debug_ll codes with RISC-V; * add support for Opencores I2C and SPI IP-blocks.
