This is not a big deal for driver code intended for Xilinx devices. <br>
Would it be acceptable for the RTEMS repository?<br></blockquote><div><br></div><div>We have never thought that was acceptable in the past. There is code for Intel</div><div>flash and if there were flash chips with the same interface (likely), then we would</div><div>have encouraged license infringement. The overarching argument is whether</div><div>inclusion of this code goes against the rule that we are promising users that</div><div>no code imposes an obligation on them.</div><div><br></div><div>In this case, my biggest concern is whether this code is truly for things </div><div>unique to Xilinx parts or is it for IP modules from ARM and Synopsys.</div><div>If for Xilinx specific IP modules, then we can debate that. </div><div><br></div><div>If the code if for ARM or Synopsys IP modules, then I am going to </div><div>come down firmly on the no side. The SoC we are working with</div><div>is a complex integration of IP from ARM, Synopsys and other</div><div>IP vendors. If the two parts we are working with share the same</div><div>IP module, then RTEMS protocol calls for it to be in shared and</div><div>used by both BSPs. We would end up with two copies of the code</div><div>with one shareable across BSPs and one locked to the Xilinx.</div><div>In this case, we are violating our guiding principle.</div><div><br></div><div>--joel</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
