While one can compile it into the kernel, we don't ship like that. There's also a question as to whether or not these files are text representation of the hardware, and there being only one way to represent it (making it not copyrightable under at least US case law since it's a database). That question hasn't been litigated. Many hardware companies also dual license the dts. Since we're not incorporating it into the kernel, but merely using it as a standardized table (there's a separate group that controls the dts/dtb spec), I think we're safe from that angle as well. There's benefit from having it in-tree because the version of the spec evolves over time, and having the right version makes it harder to push this off into a port. Also, having them in-tree makes the project's compliance with GPL a no-op because it's all there in the open in a tagged VCS. tl;dr: I don't think this is an issue. > I, too, would like less GPL in project, both in userland in kernel. > But, I can understand the desire for gcov.

While we'd like to be GPL free, let's not cut off our nose to spite our face. Given the interactions between different bits, the FreeBSD selling point of "well integrated" I think trumps the purity arguments because it's not code anybody would ever ship (and if they did, they'd get the proper warnings).
