Do you have a suggestion for another directory?<br>
<br>
If cpukit makes problems (which it clearly does due to the BSP<br>
dependencies) maybe something in bsps/shared?<br></blockquote><div><br></div><div><div class="gmail_default" style="font-size:small">The more organized way, in my opinion, will be to have the source files</div><div class="gmail_default" style="font-size:small">in their respective directories.

For small patches it would be better to send them to the list using "git<br>
send-email". That allows to comment directly on the patches. But in this<br>
case using a repo is OK because especially the import is quite big.<br></blockquote><div><br></div><div><div class="gmail_default" style="font-size:small">Once we have a decent enough patch I'll send it to the mailing list. </div></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
I'll add comments for small stuff directly on github. I hope that works ;-)<br>
