Nevermind about making a non-compliant SBI implementation.

Why make an implementation in the first place? There's no reason to use anything else than opensbi.

Because Qualcomm _really_ dislikes letting others take a look at their (usually very boring) secret sauce. Even partners working on projects shoveling revenue counted with a sizable number of digits their way.

That's also why QCSBI (or whatever they'll call it) won't be replaced by the kernel even though the architecture theoretically allows for it: That would be ceding control.
