  I was trying to debug the issue, and i found different behaviour
  with different toolchains.

Codesourcery(gcc - 4.5.2, binutils - 2.20.51)

With commit 211e47549b668c7, which is the top of master, i don't hit
the issue anymore.

ELDK-5.2(gcc - 4.6.4, binutils - 2.22)

With this toolchain, i never hit the issue. But enabling DEBUG in
board.c, i get a hang after nand initialisation. I am not able to use
debug messages, as the board starts to boot with inclusion of even a
single debug message.

I am not sure now if this is something specific to my board, as i see
different results with different toolchains. It'd be great if
this change(DEBUG enabled in board.c with an eldk toolchain) can be
checked on other boards(preferably davinci boards). Thanks.
