Please remind me, what does dtbo-y Makefile target serve for?

Rob mentioned:
https://lore.kernel.org/all/20260106192609.GA2581379-robh@kernel.org/ (local)

It'd be better to ask Rob about it, I suppose that the concern may be about
a missing in the qcom/Makefile mechanism to build standalone .dtbo artefacts.

I checked, dtbo- is not an upstream usage, it will be updated form

Right, that's why it attracted the attention.

dtbo-$(CONFIG_ARCH_QCOM) to dtb-$(CONFIG_ARCH_QCOM) in the next version.

But...
