Yes, because they expect you to go with time and use the device tree tables. I think there’s a big push to go away from these board ids and they start to not be reliable anymore. -1 probably means „don’t use it“. I have FreeScale LS1021A TWR which doesn’t even set the boardid and it’s random everytime I boot it up. But in that case you can set it in the u-boot env. One could probably patch the qemu in ports to set some other id. > The virtio ranges are present > in the vexpress-a9 and vexpress-a15 targets which annoyingly have > different load addresses and memory maps but share the same > board id. > > Seems to be an interrupt problem of some sort with the a15 > target but the a9 one works. Oh, I had enough of those… We have some changes in the Bitrig agtimer which might make it work better.

Nice, congrats, looks good. :)
