the system from the callee (M-mode) and caller (S-mode) perspective. I
think it's important to specify this for RISC-V as well, so everyone is
on the same page on what reasonable conforming implementations might
I also am not sure whether the distinction between warm and cold resets
is useful. What happens if e.g. two different SBI implementations
decided on different interpretations of what those resets entail? I
think the differences between then should be specified more thoroughly,
or they should be eliminated in favor of a single reset type.
