The virtio-serial test case I posted was 50 lines in qemu-test.  The 
virtio-serial driver is about ~1500 LOC.  That's about 3%.

I would expect that we at least have some sort of test that could verify that 
the Exynos platform more or less worked as expected.  If that was just booting a 
Linux kernel, that would be fine by me.

This is why the barrier needs to be as low as possible.
