2011-09-13omap4: make SDRAM init work for ES1.0 siliconAneesh V
SDRAM init was not working on ES1.0 due to a programming error. A pointer that was passed by value to a function was set in function emif_get_device_details(), but the effect wouldn't be seen in the calling function. The issue came out while testing for ES1.0 because ES1.0 doesn't have any SDRAM chips connected to CS1 Signed-off-by: Aneesh V <aneesh@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
2011-08-03omap4: calculate EMIF register valuesAneesh V
Calculate EMIF register values based on AC timing parameters from the SDRAM datasheet and the DDR frequency rather than using the hard-coded values. For a new board the user doen't have to go through the tedious process of calculating the register values. Instead, just provide the AC timings from the device data sheet as input and the driver will automatically calculate the register values.
