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.
