  I have checked my ais ini file, and it does the normal pll/ddr
  settings. I think it is the rbl which might be turning the cache
  ON. In any case, this patch holds true irrespective of whether rbl
  boots u-boot or spl.

  As for the question of doing away with spl and booting u-boot
  directly on hawkboard, i would want to stay with spl for now. I
  would check if we can pass the ecc layout to the nand driver in a
  clean elegant way, as Marek has suggested.
