u-boot changes for iMX8MM based custom DDR 1GB RAM

hi ,

we are making a custom board based on i.MX8M mini but the DDR is 1GB RAM.

I figured out that NXP provides a DDR tool here https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX-8M-Family-DDR-Tool-Release/ta-p/110...

and the code updates needed in u-boot as per Clock frequency and 1GB size change as mentioned in https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/iMX-8M-Mini-Register-Programming-Aid-DRA...

Any changes needed for TEE?

Hi.

This is schematic of our custom MPU module. It works perfect with 2GB RAM...but no luck with 1GB(I use MScale DDR tool with RPA configurator)
RAM part number: MT53D512M16D1DS-046 TW:D

Can someone advice where to look for changes? This particular RAM doesn't have a Bank B.
