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.
