I face the same problem some times ago because of bad bootargs passed to
the kernel from u-boot.

If you manually start the kernel from u-boot command line then you
should not set bootargs env variable to empty string (with background
idea that Linux will use default bootagrs compiled with the source). In
that case the kernel try to boot with empty bootargs and then hangs.

If it is autostart process then you should check what bootargs are set
in the config file (in u-boot/include/configs/*.h, * stand for your
specific board).

You can found a lot of information in doc file u-boot/README and on the
u-boot documentation http://www.denx.de/wiki/DULG/Manual
