that's in the fixed sdram init code, which could be considered
reasonably unreasonable by some I suppose, since we can't guarantee the
fixed settings will work with whatever memory you decide to use with
it. It should work with the memory that comes with the board, though.

btw, the spd code is being used by default on the 834x mds, not this
fixed_sdram stuff - it's mostly there for board porting completeness.
