From 5b297d1a4269308a459d123cfb91a3c91f57337c Mon Sep 17 00:00:00 2001 From: Becky Bruce Date: Fri, 17 Dec 2010 17:17:54 -0600 Subject: tqm85xx: create fixed_sdram() to do sdram setup Also, change this code to use phys_size_t instead of long int. Using common naming for this function will enable us to use the common initdram() for 85xx going forward. Other than the type change, this is just a code rearrange.
