>Description:
As noted at the top of https://releng.netbsd.org/b5reports/evbarm-earmv7hf/:

> ATF HTML reports and XML files are missing due to the lack of support for more than one block device in VEXPRESS_A15, but the console output is available.

But we have now nixed the VEXPRESS_A15 kernel config in favour of (I assume) GENERIC.  Surely, even if the VEXPRESS_A15 kernel config didn't support more than one block device, GENERIC should?  Or is this a limitation in qemu's `-M vexpress-a15' machine, despite the apparently-unused virtio0-3 devices I see in the dmesg output?  If it's really a limitation on block devices, could we use vio9p to export the results instead?
