Memory size should be specified without ECC place.
If you need to have half memory size, please change
u-boot configuration.

Michal Simek 148ba55cc6 zynq: Add new ddrc driver for ECC support 
The first 1MB is not initialized by first stage bootloader.
Check if memory is setup to 16bit mode and ECC is enabled.
If it is, clear the first 1MB.
Also u-boot should report only the half size of memory.
