Do DDR initialization using the procedural mx6_dram_cfg() instead of programming the MMDC using a raw list of register/value pairs, this solves some rare boot failures on specific "bad" modules. Calibration values, DDR geometry are unchanged, memory timings are updated according to the relevant memory datasheet, no changes on the power consumption. For IT temperature range SKUs CL is decreased from 8 to 7 and tFAW value is increased, for commercial temperature range SKUs some changes on ODT parameters. This change was validated over a range of different apalis-imx6 SoM, on the whole working temperature range with weeks of continuous testing.
