From 095aea293b70114dda0d958788a8acc15e3cd665 Mon Sep 17 00:00:00 2001 From: Aneesh V Date: Thu, 21 Jul 2011 09:10:12 -0400 Subject: omap4: calculate EMIF register values 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.
