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.
