> Why not use a devicetree register setting or Kconfig option for this value instead? A weak function  […]

As I understand it, memory capacity is CPU specific. I think it should be automatically configured by detecting the CPU model. It's not mainboard specific and so devicetree feels like the wrong place. Kconfig option might be confusing when you have the wrong CPU model.
