The legacy console is deprecated dated back to SBI version 0.2; latest firmware doesn't properly support legacy SBI extensions. This commit replaces it using latest SBI DBCN extension in RISC-V SBI 2.0. Signed-off-by: Zhouqi Jiang <[email protected]>

Thanks for your contribution! Recently I've been dealing with various projects and life events, so my availability to work on this project might be limited. When I initially wrote this project, my understanding of operating systems and Rust was limited. Hence, I'm thinking about rewriting it in the future. If that occurs, I'm happy to accept your pull request. |

The legacy console is deprecated dated back to SBI version 0.2; latest firmware doesn't properly support legacy SBI extensions. This commit replaces it using latest SBI DBCN extension in RISC-V SBI 2.0 (some code is simplified as well during this process).
