I just added "#define DEBUG" in arch/arm/lib/board to start debugging
this and for my surprise I can reach the prompt now:

I remember to have added "#define DEBUG" in v9 as well, so looks like
the behavior between v9 and v10 is consistent.

Now we need to understand why the prompt is not reached without
""#define DEBUG".
