Two things about this one:

  - what you wanted to use was $(BINARIES_DIR)/rpi-firmware/config.txt,

  - as I already replied to you earlier, please look at how it is
    done for the rpi3, and try to see if the same trick applies to
    the rpi0-w.

Thanks!

Yann E. MORIN.

In case the rpi3 fix works for rpi0-w take a look at this
patch:

	https://patchwork.ozlabs.org/patch/741230/

adding a new config/raspberrypi0w_defconfig, same as for rpi0 adding
additional 'dtoverlay=pi3-miniuart-bt' (and adding the overlay directory
to the sdcard image)...

Regards,
Peter
