I just added "#define DEBUG" in arch/arm/lib/board to start debugging this and for my surprise I can reach the prompt now: U-Boot 2013.04-rc1-14135-gab21c72-dirty (Apr 09 2013 - 09:35:51) U-Boot code: 87F00000 -> 87F2C34C BSS: -> 87F3137C CPU: Freescale i.MX31 rev 2.0 at 532 MHz.

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