This isn't really a big deal to me, as I'm only interested in RISC-V
systems, but there's been some pushback on the concept of an SBI so it
seemed like a simple way to allow people to build non-SBI (and there for not
really RISC-V) systems.

For those reading along: I suggested the /firmware/sbi node to Palmer,
because I'm interested in such "not really RISC-V" systems, (because it
makes the firmware's job easier to not implement the SBI â speaking with
my coreboot hat, here.)

One option that wouldn't require a device tree node
would be to have Linux boot in machine mode [...] and then provide its
own SBI implementation.

I think this can work.

OK, sounds good!
