2014-09-09	imx: ventana: base SPL MMDC calibration on width and size not board	Tim Harvey
	The IMX6 MMDC calibration registers depend on propagation delay and capacitive loading between the SoC's MMDC and the DDR3 chips. On the Ventana boards the board layout varies little in trace-lengths such that propagation delays are irrelevant thus we can simply things by using calibration values obtained from various board layouts based on a common SoC and DDR chip configuration. This eliminates board-model from being needed allowing more flexibility. These values were tested on a large sample size of Gateworks Ventana boards ranging in layout, and memory configuration over the entire temperature range supported.

2014-06-06	imx: ventana: switch to SPL	Tim Harvey
	Switch to an SPL image. The SPL for Ventana does the following: - setup i2c and read the factory programmed EEPROM to obtain DRAM config and model for board-specific calibration data - configure DRAM per CPU/size/layout/devices/calibration - load u-boot.img from NAND and jump to it This allows for a single SPL+u-boot.img to replace the previous multiple boa configurations.
