Nikita,
Are the values in include/configs/imx6_spl.h too inflexible to use? If
so, I can submit a patch in the future to remove that file and pull
them all in my board config files as I'm the only user of it.
This is actually something I forgot to make use of when I was rebasing
the code over mainline. I'll try to use it in a v2.
Regards,
Tim
