In theory at least this could be used for other OS's, right? Would be nice indeed, as it's part of their intended purpose. For now we have to shoehorn things into linux-only stuff (like initrd) because well, nobody cares enough about NetBSD to compile U-Boot with its internal API, so let alone adding custom Haiku code. And of course, for things linux doesn't care about (like framebuffer description) then we're stuck trying to guess where it's at and writing drivers for our bootloader. So if at least people were considering they aren't the only users of this, that'd make life better for everyone. > Perhaps QEMU is the right place to thoroughly describe this and DT and > sysfs docs can refer to it. The brilliant idea of FDT was that we could have a canonical source and blob for it where people could send patches, but of course Linux and BSD freaks disagreed, so you now find Linux-flavoured DTs for rPi and other things, as well as BSD versions. Please, at least get the binding documentation for this unique and usable for everyone!
