My point is that you could have some extra code that calls your
qe_upload_firmware() when the device tree contains the blob but the boot
loader did not already load it. This helps e.g. for the case where you
want to be able to install a generic Linux distribution that is not
able to ship with your firmware blob in the kernel or the root file system.
Putting the blob in the device tree makes it easier to get to a running
system then.

You can argue that the boot loader can always load the firmware in the
first place, but then you wouldn't need an implementation of
qe_upload_firmware in the kernel any more.
