From e6a6789f41f0560ce280089fbd3f1bd0f0f64306 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Sat, 4 Apr 2009 10:21:02 -0500 Subject: [PATCH] fsl_law: Fix bug in calculation of LAW sizing In set_ddr_laws() when we determined how much of the size requested to be mapped was covered by the the first LAW we needed to recalculate the size based on what was actually mapped.
