This is appropriate for WiFi drivers which can't continue without a firmware. For FPGAs which can be loaded, unloaded, or even partially loaded, it's the user that should trigger firmware loading, not the driver. Also, in barebox a user should decide if and when a firmware is loaded. We have cases where a single board requires different Firmwares depending on bootstrapping. In this case You don't want to have fixed firmware names. So no, the Linux Firmware model is not suitable for barebox (it sucks for Linux aswell in many cases).
