How to change DRAM size in Yocto U-Boot for iMX6

Hello Everyone,
I have a board based on imx6ullevk, with 256MB of DDR instead of the original 512MB.

I have created my custom layer and custom machine in Yocto environment but I'm having issues trying to change the DRAM size.

I have modified the memory define "PHYS_DRAM_SIZE" but I can't make the change effective once I've compiled my SD card image.

Is there a guide I can follow that shows exactly what to do to customize the u-boot parameters?

Thank you
