This commit replaces hard-coded EMIF and PHY DDR3 configurations for
predefined SODIMMs to a calculated configuration. The SODIMM parameters
are read from SODIMM's SPD and used to calculated the configuration.
The current commit supports calculation for DDR3 with 1600MHz and 1333MHz
only.

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/.
Tom,
Thank you. I'll rework the calculation not to use floating point math.
Also I'll check whether I can reuse existing drivers.
Regards,
Vitaly
