The top level qcom,msm-id and qcom,board-id are utilized by bootloaders
on Qualcomm MSM platforms to determine which device tree should be
utilized and passed to the kernel.

Is this the special magic that allows qcom bootloaders to take a kernel
plus multiple DTBs and figure out which DTB to pass?

yes

That's a bummer.

Luckily, the solution for upstream is still quite simple: Provide only
one devicetree, and it'll be used, right?

We can provide only one, we still need the IDs in the DT.

How are the DTS provided? Concatenated with the kernel, or in a
wrapped data format? Or in a separate partition from the kernel?

Its a wrapped data format that is than concatenated with the kernel if I remember correctly.
