SBI Watchdog extension?

[andreiw]

I asked in riscv-non-isa/server-soc#47 about a hardware watchdog, as feature parity-wise this is a gap, when compared to AArch64 servers. Ved pointed me at the SBI TG. Has any work started on a watchdog extension?

@andreiw : No. There was no discussion about SBI watchdog extension. Is there a hardware spec for watchdog that needed an SBI extension ? I found this but I don't think it was ratified or agreed upon.

@avpatel for confirmation.
