TDA2: What is the DDR3L RAM max size supported using 16bits data bus width at each EMIF interface?

Part Number:TDA2

What is the DDR3L RAM max size supported using 16bits data bus width at each EMIF interface?

Reference to the 'TDA2X Vision EVM Kit', if I change the RAM to 512MB (MT41K256M16TW-107) at each EMIF interface using only 16bits data bus width, can 16bits data bus able to support full 512MB RAM speed?

Do I need to modify any software configuration setting from 'Linux and RTOS Processor SDK for Vision' to have it works upon boot up?
