A new property has been added, with an extensive rationale at [1], that can be used in place of "riscv,isa" to indicate what extensions are supported by a given platform that is a list of strings rather than a single string. There are some differences between the new property, "riscv,isa-extensions" and the incumbent "riscv,isa" - chief among them for the sake of parsing being the list of strings, as opposed to a string. Another advantage is strictly defined meanings for each string in a dt-binding, rather than deriving meaning from RVI standards. This may likely to some divergence over time, but, at least for now, there's no relevant differences between the two for an M-Mode program. Add support for the new property in OpenSBI, prioritising it, before falling back to the, now deprecated, "riscv,isa" property if it is not present.
