OK, I have confirmed that on Tegra20 and Tegra30, that next-20200915 +
Marc's fix boots fine.

Tegra186 and Tegra194 are not booting, but I am wondering if this is yet
another issue that is not related. I have not actually bisected on these
boards, but I am now bisecting on Tegra186 to confirm.

Hmm ... well bisect on Tegra186 is also pointing to this commit, but the
fix is not working there. Wonder what's going on with this gic-400?

It's not GIC400. I have tons of machines with GIC400 around me, and they
don't even need the fix. What happens if you only boot the non-Denver CPUs?
