I think it is fundamentally wrong to put these #defines in the board's
memsetup.S file. The do not belong into some source file, but into the
board config file, include/configs/<name>

If we touch this part, should we not do it right, then?

Best regards,

Corinth."              - Dr. Harold Urey, Nobel Laureate in chemistry
