I think so. DDR overclocking is done from uboot via boot.ini.

Ok, I add it. No error but how can I check if it works on Debian?

If you have a usb-uart adapter you can see the frequency in the uboot messages. Otherwise try comparing results for different frequencies with a benchmark program.

Try to install and run "mbw" package on Ubuntu. You can see 5~10% of memory bandwidth increasing probably.

Over a half year later I can say that this also works on 4.14 kernel. Had now time to check this. :-D
