Interesting. Malta provides quite a few, which is what I'm using on MIPS, so I guess I've benefited from the uniformity. Since the ARM virt machine is virtual, it seems like it'd be worthwhile to make it broadly useful, and adding a few more serial outputs is basically free. Right now on build.wireguard.com, I'm just using this horrendous patch that hopefully hurts to look at: https://א.cc/iKBdlvI3/patch (since I only need 2). The goal would be for everything else to remain the same in the deployment, but to not have to use that patch. >> Could we just do the simple patch of adding four pl011s in there? > > I'm still thinking about this.

Since it's only useful for trustzone.
