Linux/AM5728: 4GB DDR support, u-boot and kernel changes

Part Number: AM5728

Tool/software: Linux

Hi,

we have an AM5728 IDK that was reworked with 4x 8Gb DDR devices, for a total of 4GB of DDR. Outside of the SDRAM_CONFIG and DDR timing changes, what other u-boot-spl and u-boot changes are required, such as LISA registers and other changes?

What Linux device tree changes are needed?

Thanks,

--Gunter
