I was kind of wondering if this is different, really, from Falcon Mode. Falcon Mode didn't initially have to factor in other-firmware as that's not a hard requirement on arm32 like it is on arm64 or risc-v. But my first read of this was that it seems like the RISC-V specific side of doing Falcon Mode and dealing with the prior stage needs correctly. -- Tom
