BTW, is the attached patch good for DTC?
I do not know when '-O dtbo' is useful,
unless I am missing something.

Subject: [PATCH] dtc: Remove -O dtbo support
This partially reverts 163f0469bf2e ("dtc: Allow overlays to have
.dtbo extension").
I do not understand why we need to support "dtbo" as --out-format.
*.dtb and *.dtbo have the same format, "dtb".
