Hi,
@Derald: Thanks for trying this out.
@Eugen: For what is worth, I can also confirm that I also tried with the latest version v2021.04 and the board boots OK out of the box with this patch only.
Ok, great news ! Thanks.
Until this patch can reach the master of u-boot, if anyone needs a tree, you can have my testing branch in u-boot-atmel custodian tree at denx:

Hi Derald,
Could I ask, you are using the SPL to boot your board ? Did you have to remove any udelay from the ddr2_init code , or it booted out of the box by applying this patch only ?
Thanks, Eugen
