There's two problems here.  The first is, no floating point math in
U-Boot.  The second is that between board/ti/ks2_evm/ddr3_spd.c that
you're adding and drivers/ddr/fsl/ddr3_dimm_params.c and
drivers/ddr/mvebu/ddr3_spd.c it seems like we have two and you would add
a 3rd file for reading the standard-defined SPD data.  We need one set
of functions in drivers/ddr/ to read the spd information and do whatever
really common bits can be done with it and the rest in
drivers/ddr/subdir/.
