Apart from build testing, what does this wider exposure achieve? Is there a
platform available that would be able to boot Linux (to a meaingful state)
with this patch series alone?
I'm mindful of merging arch code that I'm unable to test, so I'd really
rather it was merged along with the code (and a devicetree) for a platform
that can use it.
