We have this issue on Tegra a lot too; Tegra is pretty new, and so
anyone running U-Boot on Tegra typically uses the Tegra repo, not even
the ARM repo.

If we're voting, I personally fully support a move to a pure merge-based
workflow (although note that I'm not a maintainer of any part of U-Boot,
just a contributor to many Tegra boards).
