Totally agree on that! I'd love to see better testing tools. qemu has like
3 targets that we might be able to support, but the other 2 wouldn't gain
us that much since they are for hardware older than MALTA. qemu for arm has
like 50 it supports, and we could use half a dozen of them in regression
testing if we were so motivated.

There's other emulators, but none of them stray far from MALTA or something
that's so close to identical as to not be that useful. At least last time I
did a survey. I'd love someone to prove me wrong here :)
