OK, this is very odd. I've tried the ramdisk boot using the files from the CI job: Image,
modules, CPIO and my own flash.bin (u-boot and ATF hashes match those shown in
the CI job) on an EVK board and so far no hang.

What I've noticed though is that the bridge does indeed not get probed. So, for now,
I think I'm going to submit a patch to enable the driver config in the defconfig so
we can get the Verdin failures out of the way.
