Thanks for the clarification. I'm now curious if this is documented outside of random emails in svn-src-all@. I'm 100% sure I'm not the only one who needed clarification on DTS/DTB licensing, especially in the context of FreeBSD. >=20 >=20 > > I, too, would like less GPL in project, both in userland in kernel. > > But, I can understand the desire for gcov.
