I don't understand the reasoning here. These files must be at the root
of a specific FAT filesystem, so I fail to see why installing them
inside the root filesystem is of any help to achieve that.

Yes, I've seen that it's probably related to the proposed logic to
generate a bundled image in PATCH 5/5, but for the moment, my feeling
is that if that logic requires *all* files to be present in the root
filesystem to be later installed in a separate FAT/boot filesystem,
then the logic isn't really appropriate, and should be improved, no?

I believe that the existing choice of installing things in
$(BINARIES_DIR)/rpi-firmware/ was a much better choice. That's a choice
I've kept in the series on Grub/Grub2/Gummiboot, by creating a
$(BINARIES_DIR)/efi/ directory.

Best regards,

Thomas
