So what is in it for me ? If the code remains GPL, I can ask NXP for changes to the driver if I have the binary which contains this code. If the code gets re-licensed to dual GPL/BSD, I assume in certain cases, NXP will choose BSD and will not be obliged to provide the changes. I don't see any benefit for me, any way I look at it, I'm either even or loose . Why can't you use the code under the current (GPL) license anyway ? -- Best regards, Marek Vasut _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
