 Currently we are in a very early stage, trying to cross compile the AOSP codebase
 using the RISC-V official GNU toolchain. The following is the project progress log (time in reverse order).

 - 2021-01-xx Due to [open-source work](https://github.com/T-head-Semi/aosp-riscv) from T-Head(alibaba), we (PLCT lab) stopped the AOSP porting work in early 2021. All code repositories (except working-group) under the original <https://github.com/aosp-riscv> and <https://gitee.com/aosp-riscv> are backed up to [Gitee's aosp-riscv-bionic-porting](https://gitee.com/aosp-riscv-bionic-porting).
