How to init DDR on a at91sam9g45 board

How to init DDR on a at91sam9g45 board

[zzs]

dear all:

I'm using a at91sam9g45 board similar to atmel's sam9g45-ek.

So I select MACH_AT91SAM9M10G45EK in config.

first step I want to init the DDR memory, But
grep all barebox src, No code for init DDR been found.

Who can tell me, Where the DDR init code is Or barebox
can't use the DDR memory on MACH_AT91SAM9M10G45EK !?

Currently barebox relies on AT91Bootstrap to initialize SDRAM. I think
Jean-Christophe is working on changing this.
