IMX535 and DDR3, needs pull ups?

Hi,

 

Just wondering if I need any external pull ups on the data and address lines when interfacing the IMX535 with DDR3 modules (Micron MT41K512M16). Also, on page 153 of the Datasheet for the IMX535 it shows a table with "out of reset conditions" for all the IO pins (for the address and data bus for DDR3). For example it states for the pin "DRAM_A0" a config value of "LOW", does this mean no internal pull up is enabled or present on this line during reset? Thank you for your time and help.
