No, let's leave this as "firmware", as that is what the code does.

If you want to create a "load a resource from the filesystem into the
kernel" subsystem, then let's do that and then port the firmware loader
code over to use that api.

But until then, let's not try to morph the firmware code into something
that it really is not at all at the moment, just because it looks like
this might be a nice thing to do someday in the future.

sorry,
