From e66f38da8434425aca8df08d06d9ef41b3478d3b Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Wed, 1 Jul 2009 16:51:59 -0500 Subject: fsl_ddr: Fix DDR3 calculation of rank density with 8GB or more The calculate for rank density in compute_ranksize() for DDR3 used all integers for the expression, so the result was also a 32-bit integer, even though the 'bsize' variable is a u64. Fix the expression to calculate a true 64-bit value.
