[U-Boot-Users] [PATCH] harden for memory DIMM detection for AMCC Yucca 440SPe board

[Adam Graham]

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.
