Can we just update the TPL_RAM not depends on DM, and leave the code in 
the driver/ram folder,

and let the code itself to decide if use DM or not? We do use 

for dram driver code to make choice.

The core implement of PX30 DRAM driver is shared with other SoCs, it 
should be at the same place with

other SoCs.
