They just need to provide GPL code for their firmware (and they don't<br>
need to explicitly submit their device support to OpenWrt project.)<br>
BTW: It seemed that the bootrom of Qualcomm IPQ40xx comes from other<br>
Qualcomm Android chips and contains some security features that<br>
preventing unauthorized firmware to be installed on their router. An<br>
RSA pubkey can be burnt in to SoC and SoC bootrom will verify contents<br>
on flash before booting it. If this feature is used by the<br>
manufacturer you'll be impossible to flash any third-party firmware on<br>
this router.<br>
