You're right; I should have said "DT file repository" not "kernel" here. In practice, that's the Linux kernel at present though. Still, I stand by my assertion that the values U-Boot expects for DTB filenames make sense, and we should update any/all repositories of DTB files so there is a complete set of matching files. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
