I can certainly do a readme file. Is there a way to build U-Boot with two different device tree options? The SOM-LV and Torpedo have separate device trees. The original code had a mechanism to autodetect which hardware was being used and would then select the corresponding dtb. With the device tree integrated into U-Boot it seemed to me like the auto detect code didn't make sense since the U-Boot with the corresponding DTB would have to be loaded from the beginning. I looked at the variety of am33xx boards, and it seemed like different versions have different _defconfig files. I would prefer to have a since defconfig and separate U-Boot files generated for each DTB, but it wasn't clear to me whether or not that was possible. If you have an example I can look at that and redo this to eliminate the second defconfig. adam > > -- > Tom _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
