Can you name this something different. We already have something called fastboot in-tree (the Android-derived protocol) and there's a Microsoft technology called fastboot (some kind of hibernation). "OS Boot" isn't very specific either, since we (almost always) boot an OS. Maybe "Eagle mode" by analogy to Falcon mode, which lets SPL directly boot an OS.
(Is this substantially different from falcon mode anyway?)
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.
