U-Boot is compiled for a single board, which in turn uses a specific SoC. There's no need to make runtime decisions based on SoC ID. While there's certainly an argument for making the code support different SoCs at run-time, the Tegra code is so far from that possible ideal that the existing runtime code is an anomaly. If this changes in the future, all runtime decisions should likely be based on DT anyway.

What exactly is missing to prevent multi-arch support? Shouldn't we head towards that rather than making it harder?
