The kernel doesn't do anything with that node though, so if you were to load a fitImage in U-Boot containing this DT, having booted with whatever the factory provided OpenSBI has, that limitation doesn't apply, right? > However, minimal th1520 > support is better than nothing.

Although I assume it is fine since v2 was nearly fine!
