shared linkcmds if any that are arch-independent) and avoid<br>
duplications, and only include the relevant parts of your HiFive<br>
boards, similar to ARM-based BSPs.<br>
<br>
It's important you try to address comments/feedback; students should<br>
go through the code review process, etc it's one of the goals of<br>
Google Summer of Code and open-source involvement.<br>
