Hi Simon,

You have added one more cfg file in this patch
Now you have three cfg files in this folder that just diff from each other for DRAM configuration.

Whereas you can delete two of them, use maximum dram setting in cfg file, and then in board specific file you can tune the configuration for required size.

You may look for this optimization.
FYI: pls see the captured log of diff
