What do do with unconnected DDR3 balls in a 32-bit configuration of iMX6Solo?

Hello,

Since the iM6Solo only supports 32-bit memory bus, but have balls for a 64-bit memory bus it is unclear to me how I should connect these 32 unused balls. Should they just be left unconnected?

Thanks!

Unused signals / pins of 64-bit memory I/F (in 32-bit mode) may be left free,

as stated  in section 5 (DRAM interface requirements for migration) of app

note AN4397 (Common Hardware Design for i.MX 6Dual/6Quad and i.MX 6Solo/6DualLite)
