[Yaffs] suitable kernel versions

Hello.

This is my first message to this list. I hope I am in the right place.
It seems a bit hard to find up to date documentation about yaffs in
the internet.

I am trying to compile it against a 3.4 kernel. Is that too
up-to-date? The error I get is this:

$ LANG= make

I guess it's missing something in the mtd foundations, in my kernel
sources. But I am not really familiar with that part of the kernel.
Should I just pick another kernel, wait or try to hack something
myself (guidance on where to look is appreciated ;) ).

Thank you :)
