From f5577aae4aa9f245c4c67308fe0f7b3cecf61c93 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Tue, 29 Aug 2006 08:04:32 +0200 Subject: Improve DIMM detection for AMCC Yucca 440SPe board Improved the memory DIMM detection for the Yucca 440SPe board for the case where a memory DIMM is falsely detected as present. This issue is seen on some AMCC Yucca 440SPe validation boards if only one 512MB memory DIMM is installed, i.e. DIMM slot 0 is populated and DIMM slot 1 is empty. In this case, U-Boot does not correctly detect that there is only one DIMM memory module installed and will falsely detect two DIMM memory modules are present and therefore U-Boot will not calculate the correct amount of total memory and u-boot will not booting up.
