完整支持buildroot 2021 LTS构建D1开发板SD卡系统镜像

[baiwen]

完整支持使用社区buildroot 2021自动编译构建D1 TF卡启动镜像，可以专门用来研究D1启动流程 工具链或者研究各个部分 boot0 opensbi u-boot kernel rootfs 等 对于深入理解RISC V 64有很大的帮助，目前正在整理合并源码 预计下周之前可以发布 获取最新动态请关注 https://gitee.com/weidongshan/neza-d1-buildroot.git

韦老师，这是什么问题呢？

[IAMLIUBO]

哇，这个好，最近搞M5Pi，刚好也比较熟悉buildroot了

[baiwen]

@whycan 参考 我们那个git仓库里 对buildroot opensbi 包做的修改 以及opensbi源码的修改。

[qianhao]

@whycan 这条指令是平头哥扩展指令集的，一般的编译器会出问题吧，
