Have you tested this against a real hardware pl031? I appreciate
that the scaffolding to let you do that is probably pretty
painful, but it would be interesting to test, because I'm
not really all that confident in the accuracy of QEMU's
pl031 model. (Notably there are some places where it absolutely
does not work like the real h/w; in some ways it's a bit
like "a pl031 that some imaginary firmware has initialized
and enabled"...)
thanks
