Thanks for review ! I didn't notice they moved all the blobs into a
separate git repository. I assume you mean the same approach as in
the package linux-firmware.mk: adding separate Kconfig options
for each group of firmware files.

I will rework xr819 firmware packaging approach and then resubmit
the whole patchset. For the time being I plan to add xr819 and ap6212
sub-options to handle orange-pi-zero and upcoming orange-pi-zero-plus2 boards.
