How to get U-boot work with 4GByte Memory for iMX6DL

The register to physically access 4GByte DDR3 RAM is set to:

        0x021b0040, 0x0000007F   

Memory above 2GByte is physically available and we can read/write using U-boot md/mw commands.

 

When CONFIG_DDR_MB is set to 2048, U-boot is fine.

 

But when we make CONFIG_DDR_MB above 2048 (more than 2GByte)  and it does not work, U-boot freezes when it tries to relocate itself.

 

What else needs to be changed?

Selcuk
