But the goal here is to have platform specific firmwares so that's fine? So long as we come up with something stable and platform specific userspace will have the information to provide the firmware it likes, even if that does end up involving a lot of symlinks. > All of the qcom platforms use firmware-name from DT to get the full firmware > path with name. > I know this has scaling issues, but with the current state of things, its > the only option I see. When you say "all the qcom platforms" what do you mean, you're proposing a new property here?
