further clarify or not the RISC-V ISA thing that's elsewhere in this thread (and part of the kernel, not a U-Boot thing).

TBH, this a bit fragmented across threads, and as someone that hasn't been following it it's a bit difficult to tell exactly what is being asked for. Would someone be able to ask it as a direct question?

Sorry for being unclear, and thanks for asking. What I think the U-Boot community would like to know is, what is the device-tree based way to know if a RISC-V platform has the Zbb extensions and so the RNG opcodes, similar (in concept at least?) to the ARMv8.5 RNG feature.
