Subject: [PATCH v2 00/12] Add initial RISC-V architecture support
Date: Thu, 28 Jun 2018 10:39:41 +0300	[thread overview]
Message-ID: <20180628073953.15384-1-antonynpavlov@gmail.com> (raw)

This patchseries adds initial RISC-V architecture support for barebox.

See Documentation/boards/riscv.rst for instructions.

You can obtain this patchseries from github:

    $ git clone -b 20180628.riscv https://github.com/frantony/barebox

    * drop skeleton.dtsi;
    * drop SPI GPIO bindings for erizo_generic;
    * improve erizo-nmon-image;
    * generic linker script is dropped;
    * use generic GCC library routines from lib.

    * 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):
