Re: [U-Boot] [RFC PATCH] arm: mx6: Clamp MMDC and DDR3 clocks for timing calculations

This is proposal for clamping the MMDC/DDR3 clocks to the maximum supported frequencies as per imx6 SOC models, and for dynamically calculating valid clock value based on mem_speed.

Currently the code uses impossible values for mem_speed (1333, 1600 MT/s) for calculating the DDR timings, and uses fixed clock (528 or 400 MHz) which doesn't take into account DDR3 memory limitations.
