I tried testing this on OSK board. If I boot with earlyprintk disabled,
it boots OK and everything works (also CF card) with your playground
commit 5723b6686943.

However with earlyprintk it seems to hang as soon as kernel tries to print
something. So something goes wrong with early DEBUG_LL mapping code when
CONFIG_DEBUG_UART_VIRT=0xff000000 is used?
