If you "cat" all the files in "/sys/i4b" and search for the word "linux" or "Linux" you will get some hits. So I suspect that some parts of the drivers in "/sys/i4b/layer1" are derivatives of Linux. And I have got some hints about that too. So maybe we should just drop support for some hardware, and stick with the chip-drivers I have written from scratch ? Else we might end up getting a bad rumor about stealing code from Linux. Does anyone have any opinion about what is allowed and what is not allowed ? --HPS
