It works perfetcly with 4.1.2 release.

I'm trying to use stmmac within cubietruck (sunxi).

i think it worked within 4.1.2 because it had separade sunxi driver, now it is in stmmac.

There wasn't a separate driver in < 4.1 but there has been some re-factoring that landed in 4.2 [0] that broke it, I suspect the patch author didn't test it with a modular build. I'm looking at it when I get the time but I'm hoping someone will fix it upstream

yes, I sent this bug also to maillist and when Joachim Eastwood will have a patch - I will test it.
