The firmware loading mechanism in Linux is driven by the driver
requesting a firmware. 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).
