Ok, I just built an u-boot and two 3.17.1 kernels for versatile express,
which I then loaded via qemu. The result is the same as for mvebu, i.e.
w/o OF_SELFTEST the first kernel just boots as expected and the second
kernel compiled w/ OF_SELFTEST hangs. Both kernels are built w/ appended
dtb support.
