This isn't really a big deal to me, as I'm only interested in RISC-V

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.
