@Peter Maydell this has been reviewed, do you mind taking this in you
next PR? I don't see a maintainer for hw/rtc.
It would be great if this series can be taken for QEMU-4.2
It doesn't look like there's anyone who maintains hw/rtc, so maybe that's why
this has been going slowly? I'd happy to PR it, but I don't really have the
bandwidth to sign up to maintain more stuff right now.
