Please note that this introduces build failure on the tricorder
platforms but is a bugfix.  Thomas, tricorder is currently broken in
that NAND doesn't work without this patch.  With this patch we're now
too big in SPL to fit in SRAM.  I suspect, but this needs run-time
testing that we can bump max size / say 6KB for stack, or better yet
confirm that like am335x / am43xx / omap4+ we init DDR prior to putting
CONFIG_SPL_STACK into sp and can use the whole of SRAM for SPL and have
stack be an address in DDR (see
http://patchwork.ozlabs.org/patch/371636/).

Applied to u-boot-ti/master, thanks!
