First, get a git checkout of Marvell's u-boot stuff:
  git clone git://git.denx.de/u-boot-marvell.git

Make sure you have the 'master' branch checked out:
  git checkout master

Now build the new u-boot.kwb image:
  make guruplug_config
  make
  ./tools/mkimage \
    -n ./board/Marvell/guruplug/kwbimage.cfg \
    -T kwbimage \
    -a 0x00600000 \
    -e 0x00600000 \
    -d u-boot.bin \
    u-boot.kwb
