Thanks for the explanation. At the beginning I was wondering what the
point of this line was, and thought that a comment that explains the
purpose of it would be beneficial.
Maybe it makes sense to provide a section so that other contributors
know where to sort in their tests, so maybe
# Overlays
dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3588-edgeble-neu6a-wifi.dtb
[...]
# Compile-time tests for overlays (and combinations thereof)
rk3588-edgeble-neu6a-wifi-dtbs := rk3588-edgeble-neu6a-io.dtb
rk3588-edgeble-neu6a-wifi.dtbo
[...]
But this is simply a recommendation.
Regards, Michael
