The firmware loader exports APIs that can be called by core to load and
process multiple different file formats.

I don't see how it's used. Perhaps you need to check code with `make W=1`.
Darn, we missed this one. I thought we were using W=1 on github but we
aren't, this will be fixed.
Though W=1 doesn't report this one, so need to re-inspect this. Thanks
for the sighting.

Hmm... Why do we need a kernel level duplication in words?
Not sure I get this one, it's just a warning message where you don't
copy a block of size zero into the target memory.

Noise.
Better to introduce a trace points and drop all these kind of messages.
it's not that bad, most people understand what dmesg is, it happens once
and only if you have dynamic debug.
At some point we also thought about something like drm_debug where you
can specify which parts you are interested in, in addition to the
verbosity level.
