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.
