RAM configuration with Device tree

I'm working on a board close to the at91sam9g25ek board.

One of the main difference is the DDR2 that is not exactly the same.
In the device tree, there is this:

ramc0: ramc@ffffe800
compatible = "atmel,at91sam9g45-ddramc";
reg = <0xffffe800 0x200>;

In the .c file, I could not find any thing about ram configuration. I would like to change param such as TRP (row precharge delay)
How could I do this?
