first, this is effectively a Linux issue, so you are mostly off topic
here.
Second, it's very difficult to help at all if all you provide is some
vague statement without any details like an exact description of what
you attempted to do and what the result was - including for example a
complete boot log.
So I can only guess... It seems you are trying to pass MTD partition
information to Linux by using the mtdargs boot argument, and this
doesn't work. Well, perhaps your Linux kernel is not configured to
use such information at all? Eventually it takes the informantion
from somewhere else, like from the device tree?
Best regards,
Wolfgang Denk
