From d26154c9a692586b66eb6d1f8e1b67c75e40ea70 Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Thu, 11 Sep 2008 21:35:36 +0400 Subject: mpc83xx: spd_sdram: fix ddr sdram base address assignment bug The spd_dram code shifts the base address, then masks 20 bits, but forgets to shift the base address back. Fix this by just masking the base address correctly. Found this bug while trying to relocate a DDR memory at the base != 0.
